Beetles

Understanding Beetles


Beetles are one of the largest groups of insects in the world and play many different roles in Texas ecosystems. While many beetles are beneficial and help decompose organic matter, pollinate plants, or control pests, some species can cause significant damage to trees by feeding on bark, wood, leaves, roots, or foliage.


Texas is home to numerous beetle species that affect both urban landscapes and native forests.


Common Tree-Damaging Beetles in Texas


 Bark Beetles


Bark beetles attack the inner bark of trees, disrupting the movement of water and nutrients.

Common hosts:

  • Pine trees
  • Spruce
  • Fir
  • Other conifers

Symptoms:

  • Small holes in bark
  • Sawdust-like material
  • Yellowing needles
  • Tree decline


Ips Engraver Beetles


Commonly attack stressed or damaged pine trees.

Symptoms:

  • Browning needles
  • Pitch tubes on bark
  • Rapid decline


 Emerald Ash Borer


An invasive beetle that attacks ash trees.

Symptoms:

  • Canopy thinning
  • D-shaped exit holes
  • Branch dieback
  • Tree mortality


 Longhorned Beetles


Wood-boring beetles whose larvae tunnel through trunks and branches.

Symptoms:

  • Large exit holes
  • Internal wood damage
  • Weak limbs


Signs of Beetle Infestations


Common indicators include:

  • Small holes in bark
  • Sawdust around the tree base
  • Peeling bark
  • Dead branches
  • Canopy thinning
  • Woodpecker activity
  • Exit holes on trunks and limbs
  • Rapid tree decline


Why Beetles Attack Trees


Many beetles are attracted to:

  • Drought-stressed trees
  • Storm-damaged trees
  • Recently injured trees
  • Diseased trees
  • Newly cut wood

Healthy trees are generally more resistant to beetle attacks.


Are All Beetles Harmful?


No. Many beetles provide important environmental benefits.

Beneficial beetles include:

  • Lady beetles (ladybugs)
  • Ground beetles
  • Dung beetles
  • Pollinating beetles
  • Decomposer beetles

These insects help maintain healthy ecosystems and can even reduce pest populations.


Prevention Tips


  • Water trees during drought
  • Avoid damaging trunks and roots
  • Remove storm-damaged limbs promptly
  • Maintain overall tree health
  • Monitor for early signs of infestation
  • Schedule routine tree inspections


Why Early Detection Matters


Many beetle infestations begin before visible symptoms appear. Early identification can help reduce tree stress, prevent the spread of damaging insects, and improve the likelihood of preserving valuable trees.


At CBM Tree Service, tree health assessments can help identify beetle activity, evaluate tree condition, and provide recommendations to protect trees throughout Texas from insect-related damage. 

Bark Beetles

Understanding Bark Beetles


Bark Beetles are small wood-boring insects that live and reproduce beneath the bark of trees. While many species naturally help break down dead and dying trees, some bark beetles can become serious pests when they attack stressed, weakened, or drought-affected trees.


In Texas, bark beetles are most commonly associated with pine tree decline, especially during periods of drought, storm damage, or other environmental stress.


Common Trees Affected in Texas


  • Loblolly Pine
  • Shortleaf Pine
  • Slash Pine
  • Longleaf Pine
  • Ponderosa Pine
  • Other conifer species


What Do Bark Beetles Look Like?


Bark beetles are typically:

  • Very small (about 1/16 to 1/4 inch long)
  • Brown, black, or reddish-brown
  • Cylindrical in shape
  • Difficult to see without close inspection

Most damage is caused by the larvae feeding beneath the bark.


Signs & Symptoms of Infestation


Common indicators include:

  • Small round holes in the bark
  • Sawdust-like material on the trunk or ground
  • Resin or pitch tubes on the bark
  • Peeling or loose bark
  • Yellowing needles
  • Browning foliage
  • Thinning canopy
  • Woodpecker activity on the trunk

Trees often show symptoms from the top down as water movement becomes disrupted.


How Bark Beetles Damage Trees


Adult beetles tunnel beneath the bark and lay eggs. The larvae then create feeding galleries that interrupt the flow of water and nutrients between the roots and canopy.

Heavy infestations can:

  • Weaken trees
  • Cause branch dieback
  • Reduce growth
  • Kill entire trees

Some bark beetles also introduce fungi that contribute to tree decline.


Common Bark Beetles in Texas

Southern Pine Beetle


One of the most destructive forest pests in the southeastern United States.

Symptoms:

  • Pitch tubes
  • Rapid needle discoloration
  • Tree mortality


Ips Engraver Beetles


Frequently attack drought-stressed or storm-damaged pines.

Symptoms:

  • Reddish-brown needles
  • Bark galleries
  • Rapid decline


Black Turpentine Beetle


Often attacks the lower portion of pine trunks.

Symptoms:

  • Large pitch tubes
  • Reduced vigor
  • Slow decline


Why Trees Become Vulnerable


Bark beetles are attracted to:

  • Drought stress
  • Storm damage
  • Lightning strikes
  • Construction injury
  • Soil compaction
  • Disease
  • Recently cut or damaged trees

Healthy trees can often defend themselves by producing resin that pushes beetles out.


Prevention Tips


  • Water trees during extended drought
  • Avoid damaging roots and trunks
  • Remove severely infested trees promptly
  • Clean up storm debris
  • Maintain proper mulch rings
  • Monitor pines regularly for early signs of attack


Why Early Detection Matters


Bark beetle infestations can spread quickly and may kill trees before symptoms become obvious. Identifying infestations early can help reduce losses and protect nearby trees from attack.


At CBM Tree Service, tree health assessments can help identify bark beetle activity, evaluate tree condition, and provide recommendations to help protect valuable trees throughout Texas. 

Southern Pine Beetle

Understanding Southern Pine Beetle


The Southern Pine Beetle (SPB) is one of the most destructive forest pests in the southeastern United States and can cause significant damage to pine trees in Texas. These small bark beetles attack the inner bark of pine trees, disrupting the flow of water and nutrients and often killing the tree within a relatively short period of time.


Southern Pine Beetles are especially problematic during periods of drought, overcrowding, storm damage, or other environmental stresses that weaken trees.


Common Trees Affected


  • Loblolly Pine
  • Shortleaf Pine
  • Slash Pine
  • Longleaf Pine
  • Virginia Pine
  • Other pine species


What Do Southern Pine Beetles Look Like?


Adult beetles are:

  • About 1/8 inch long
  • Reddish-brown to black
  • Cylindrical in shape
  • Difficult to see without close inspection

The larvae are small, white, legless grubs that develop beneath the bark.


Signs & Symptoms of Infestation


Common warning signs include:

  • Small pitch tubes on the bark
  • White, yellow, or reddish-brown resin deposits
  • Tiny entrance holes in the trunk
  • Sawdust-like material in bark crevices
  • Yellowing needles
  • Needles turning red or brown
  • Rapid canopy decline
  • Woodpecker activity

Infested trees often change from green to yellow and then reddish-brown as the attack progresses.


How Southern Pine Beetles Damage Trees


Adult beetles bore through the bark and create tunnels where they lay eggs.

The developing larvae:

  • Feed beneath the bark
  • Create winding galleries
  • Disrupt nutrient movement
  • Prevent water from reaching the canopy

In addition, Southern Pine Beetles often introduce blue-stain fungi that further weaken the tree.


Why Southern Pine Beetles Are Dangerous


Southern Pine Beetles can:

  • Kill healthy pine trees
  • Spread rapidly through pine stands
  • Cause large-scale forest damage
  • Increase wildfire fuel loads
  • Create hazards from dead trees

Outbreaks can affect dozens or even hundreds of trees if left unmanaged.


Why Trees Become Susceptible


Risk factors include:

  • Drought stress
  • Overcrowded pine stands
  • Storm damage
  • Lightning strikes
  • Soil compaction
  • Construction injury
  • Disease or poor tree health

Healthy trees are generally better able to resist attacks by producing resin that helps repel beetles.


Prevention Tips


  • Maintain tree health through proper watering
  • Avoid damaging roots and trunks
  • Thin overcrowded pine stands when appropriate
  • Remove severely infested trees promptly
  • Monitor pines regularly during drought periods
  • Schedule routine tree inspections


Can Infested Trees Be Saved?


Once a tree is heavily infested, recovery is unlikely. Early detection is critical because treatment options become limited after beetles establish extensive galleries beneath the bark.


Why Early Detection Matters


Southern Pine Beetles can spread quickly from tree to tree. Identifying infestations early can help reduce losses, protect nearby pines, and prevent widespread damage to landscapes and forested properties.


At CBM Tree Service, tree health assessments can help identify Southern Pine Beetle activity, evaluate tree condition, and provide recommendations to help protect valuable pine trees throughout Texas. 

Ips Engraver Beetles

Understanding Ips Engraver Beetles


Ips Engraver Beetles are a group of bark beetles that commonly attack pine trees throughout Texas. Their name comes from the distinctive engraved-looking galleries they create beneath the bark as they tunnel and reproduce.


These beetles are considered secondary pests, meaning they typically attack trees that are already stressed by drought, storm damage, construction injury, lightning strikes, or other environmental factors. However, large populations can sometimes overwhelm and kill otherwise healthy trees.


Common Trees Affected in Texas


  • Loblolly Pine
  • Shortleaf Pine
  • Slash Pine
  • Longleaf Pine
  • Virginia Pine
  • Other pine species


What Do Ips Engraver Beetles Look Like?


Adult beetles are:

  • Small, usually 1/8 to 1/4 inch long
  • Brown to dark reddish-brown
  • Cylindrical in shape
  • Equipped with a scooped-out rear end lined with small spines

Most damage occurs beneath the bark where the beetles live and reproduce.


Signs & Symptoms of Infestation


Common indicators include:

  • Small holes in the bark
  • Fine sawdust (frass) around the trunk
  • Peeling bark
  • Yellowing needles
  • Needles turning reddish-brown
  • Thinning canopy
  • Woodpecker activity
  • Branch dieback

Infested trees often show discoloration beginning in the upper canopy.


How Ips Engraver Beetles Damage Trees


Adult beetles bore through the bark and create tunnels where they lay eggs.

The larvae then:

  • Feed beneath the bark
  • Create characteristic engraving-like galleries
  • Disrupt water and nutrient transport
  • Weaken the tree

Heavy infestations can eventually kill the tree.


Why Trees Become Vulnerable


Ips beetles are attracted to:

  • Drought-stressed trees
  • Lightning-damaged trees
  • Storm-damaged pines
  • Freshly cut pine logs
  • Construction-damaged roots
  • Fire-damaged trees
  • Trees weakened by disease

Healthy pines often defend themselves by producing resin that helps push beetles out.


What Do Ips Galleries Look Like?


One of the most recognizable signs is the gallery pattern beneath the bark.

These galleries often appear as:

  • Y-shaped or star-shaped tunnels
  • Etched patterns in the wood
  • Egg galleries radiating outward from a central chamber

These markings give the beetles their "engraver" name.


Why Ips Beetles Are Important


Ips beetles can:

  • Kill weakened pine trees
  • Spread rapidly during drought conditions
  • Increase fire hazards by creating dead trees
  • Reduce property aesthetics
  • Contribute to forest decline


Prevention Tips


  • Water pines during prolonged drought
  • Avoid damaging trunks and roots
  • Remove storm-damaged pine material promptly
  • Dispose of freshly cut pine debris quickly
  • Maintain overall tree health
  • Monitor pine trees regularly


Can Infested Trees Be Saved?


Trees caught early may survive if infestations are light and tree health improves. However, heavily infested trees often decline rapidly and may require removal to reduce beetle populations.


Why Early Detection Matters


Ips Engraver Beetles can complete multiple generations each year in Texas. Early identification of symptoms can help prevent the loss of valuable pine trees and reduce the risk of infestations spreading to nearby trees.


At CBM Tree Service, tree health assessments can help identify Ips Engraver Beetle activity, evaluate tree condition, and provide recommendations to help protect valuable pine trees throughout Texas. 

Black Turpentine Beetle

Understanding Black Turpentine Beetle


The Black Turpentine Beetle (Dendroctonus terebrans) is the largest bark beetle commonly found attacking pine trees in the southern United States, including Texas. Unlike some bark beetles that attack the upper portions of a tree, Black Turpentine Beetles typically infest the lower trunk near the base of pine trees.


These beetles are often attracted to trees that have been stressed, injured, or weakened by drought, construction damage, storms, fire, or other environmental factors.


Common Trees Affected in Texas


  • Loblolly Pine
  • Slash Pine
  • Shortleaf Pine
  • Longleaf Pine
  • Virginia Pine
  • Other pine species


What Do Black Turpentine Beetles Look Like?


Adult beetles are:

  • Dark reddish-brown to black
  • About 1/4 to 3/8 inch long
  • Larger than most other bark beetles
  • Cylindrical in shape

Larvae are:

  • White
  • Legless
  • Found beneath the bark


Signs & Symptoms of Infestation


Common indicators include:

  • Large pitch tubes on the lower trunk
  • White, pink, or reddish resin masses
  • Boring dust around the tree base
  • Bark cracks and damage
  • Yellowing needles
  • Crown thinning
  • Reduced tree vigor

Pitch tubes produced by Black Turpentine Beetles are often much larger than those created by Southern Pine Beetles.


How Do They Damage Trees?


Adult beetles bore through the bark and create tunnels where they lay eggs.

The developing larvae:

  • Feed beneath the bark
  • Damage the cambium layer
  • Disrupt water and nutrient movement
  • Weaken the tree's defenses

Heavy infestations can contribute to tree decline and increase susceptibility to other pests and diseases.


Why Trees Become Vulnerable


Black Turpentine Beetles are attracted to:

  • Drought-stressed trees
  • Storm-damaged pines
  • Lightning-struck trees
  • Construction injuries
  • Soil compaction
  • Root damage
  • Recently transplanted trees

Healthy trees can often resist attacks by producing resin that helps expel invading beetles.


Why Are Black Turpentine Beetles Important?


Although they rarely cause large outbreaks like Southern Pine Beetles, they can:

  • Weaken valuable landscape pines
  • Accelerate decline in stressed trees
  • Create entry points for disease organisms
  • Increase the likelihood of tree mortality when combined with other stress factors

Prevention Tips


  • Water pine trees during extended droughts
  • Avoid damaging trunks and roots
  • Protect trees during construction projects
  • Maintain mulch around the root zone
  • Remove severely damaged trees promptly
  • Monitor pines regularly for pitch tubes near the base


Can Infested Trees Be Saved?


Many healthy trees can survive light infestations if stress factors are corrected. However, trees already weakened by drought, root damage, or disease may continue to decline.


Why Early Detection Matters


Large pitch tubes near the base of a pine tree are often the first visible sign of Black Turpentine Beetle activity. Early identification can help property owners address tree stress, improve tree health, and reduce the risk of further damage.


At CBM Tree Service, tree health assessments can help identify Black Turpentine Beetle activity, evaluate tree condition, and provide recommendations to help protect valuable pine trees throughout Texas. 

Emerald Ash Borer

Understanding Emerald Ash Borer


The Emerald Ash Borer (EAB) is a highly destructive invasive beetle that attacks and kills ash trees. Native to Asia, this insect was first discovered in North America in 2002 and has since caused the death of millions of ash trees across the United States.


The beetle's larvae feed beneath the bark, destroying the tree's vascular system and preventing the movement of water and nutrients. Without treatment, most infested ash trees die within a few years.


Common Trees Affected


All native ash species are susceptible, including:

  • Green Ash
  • White Ash
  • Black Ash
  • Texas Ash
  • Arizona Ash
  • Blue Ash


What Does Emerald Ash Borer Look Like?


Adult beetles are:

  • Metallic emerald-green
  • About 1/2 inch long
  • Slender and bullet-shaped
  • Active during late spring and summer

Larvae are:

  • Cream-colored
  • Flattened and segmented
  • Found beneath the bark


Signs & Symptoms of Infestation


Common indicators include:

  • Thinning canopy
  • Dieback in upper branches
  • Yellowing leaves
  • Sprouting shoots along the trunk
  • Increased woodpecker activity
  • Bark splitting
  • D-shaped exit holes
  • Progressive canopy decline

Symptoms often begin in the upper canopy before becoming visible throughout the tree.


How Emerald Ash Borers Damage Trees


Adult beetles lay eggs on the bark of ash trees.

After hatching, larvae:

  • Tunnel beneath the bark
  • Feed on the cambium layer
  • Create S-shaped galleries
  • Disrupt water and nutrient transport

As damage increases, the tree becomes unable to support healthy growth.


What Are D-Shaped Exit Holes?


One of the most recognizable signs of Emerald Ash Borer activity is the presence of:

  • Small D-shaped exit holes
  • Approximately 1/8 inch wide
  • Located on trunks and branches

These holes are created when adult beetles emerge from the tree.


Why Emerald Ash Borers Are Dangerous


Emerald Ash Borers can:

  • Kill otherwise healthy ash trees
  • Spread rapidly across large areas
  • Cause extensive tree loss
  • Create hazardous dead trees
  • Increase removal costs
  • Impact urban forests and landscapes

Untreated infestations are often fatal.


Prevention & Management


Management options may include:

  • Regular inspections
  • Early detection monitoring
  • Systemic insecticide treatments
  • Maintaining overall tree health
  • Removal of severely infested trees
  • Proper disposal of infested wood

Treatment is often most effective before significant canopy decline occurs.


Why Early Detection Matters


Emerald Ash Borers can infest a tree for several years before obvious symptoms appear. By the time canopy decline becomes noticeable, extensive internal damage may already exist.


Early identification can help preserve valuable ash trees, reduce hazards, and improve treatment success rates.


At CBM Tree Service, tree health assessments can help identify Emerald Ash Borer activity, evaluate tree condition, and provide recommendations to help protect valuable ash trees throughout Texas. 

Longhorned Beetles

Understanding Longhorned Beetles


Longhorned Beetles are a group of wood-boring insects known for their exceptionally long antennae, which can be as long as or longer than their bodies. While many species play an important role in breaking down dead and decaying wood, some can damage living trees by tunneling through trunks, branches, and stems.


Texas is home to numerous native longhorned beetle species, and several invasive species have become concerns in North America due to their ability to kill healthy trees.


Common Trees Affected in Texas


  • Oak
  • Ash
  • Elm
  • Maple
  • Cottonwood
  • Sycamore
  • Pecan
  • Mesquite
  • Pine species
  • Various ornamental trees


What Do Longhorned Beetles Look Like?


Adult beetles are typically:

  • Large and elongated
  • Brown, black, gray, or patterned
  • Equipped with very long antennae
  • Usually 1/2 inch to over 2 inches long

Larvae are:

  • Cream-colored
  • Legless
  • Commonly called "roundheaded borers"

Signs & Symptoms of Infestation


Common indicators include:

  • Round or oval exit holes in bark
  • Sawdust-like material (frass)
  • Branch dieback
  • Bark cracking
  • Weakened limbs
  • Internal wood tunnels
  • Tree decline
  • Increased woodpecker activity

Many symptoms may not appear until significant internal damage has occurred.


How Longhorned Beetles Damage Trees


Adult beetles lay eggs in bark crevices or wounds.

After hatching, larvae:

  • Bore into wood
  • Create tunnels within trunks and branches
  • Feed on internal tissues
  • Weaken structural integrity

Severe infestations can reduce tree vigor and increase the risk of limb failure.


Common Longhorned Beetles Found in Texas


Redheaded Ash Borer


Often found in weakened hardwood trees.


Cottonwood Borer


A large native beetle commonly associated with cottonwood trees.


Pine Sawyer Beetles


Frequently found in dying or recently dead pine trees.


Asian Longhorned Beetle (Invasive Concern)


A highly destructive invasive species capable of killing healthy hardwood trees.


Why Trees Become Vulnerable


Longhorned beetles are often attracted to:

  • Drought-stressed trees
  • Storm-damaged trees
  • Fresh wounds
  • Dead or declining trees
  • Recently cut wood
  • Construction-damaged roots

Healthy trees are generally less susceptible to serious infestations.


Why Longhorned Beetles Are Important


These beetles can:

  • Accelerate wood decay
  • Weaken tree structure
  • Cause branch failure
  • Reduce timber value
  • Create hazards in urban landscapes

However, many native species also help recycle dead wood and contribute to healthy forest ecosystems.


Prevention Tips

  • Maintain proper tree health
  • Water during extended droughts
  • Avoid unnecessary trunk injuries
  • Remove dead or severely damaged limbs
  • Monitor trees for exit holes and sawdust
  • Schedule routine tree inspections


Can Infested Trees Be Saved?


Trees with light infestations may recover if overall health improves. However, trees experiencing extensive internal tunneling or structural weakness may require pruning or removal to reduce safety risks.


Why Early Detection Matters


Longhorned beetle larvae can live inside wood for months or even years before adults emerge. Early identification can help prevent extensive damage, preserve valuable trees, and reduce the likelihood of branch or trunk failure.


At CBM Tree Service, tree health assessments can help identify Longhorned Beetle activity, evaluate structural risks, and provide recommendations to help protect valuable trees throughout Texas. 

Redheaded Ash Borer

Understanding Redheaded Ash Borer


The Redheaded Ash Borer (Neoclytus acuminatus) is a native longhorned beetle found throughout Texas and much of North America. Despite its name, it is not limited to ash trees and can be found in a variety of hardwood species. The beetle is best known for its reddish head and yellow-striped black body, which can resemble a wasp.


Unlike highly destructive invasive pests such as the Emerald Ash Borer, Redheaded Ash Borers typically attack stressed, injured, dying, or recently dead trees rather than healthy trees.


Common Trees Affected in Texas


  • Ash
  • Oak
  • Elm
  • Hickory
  • Pecan
  • Cottonwood
  • Maple
  • Hackberry
  • Other hardwood species


What Do Redheaded Ash Borers Look Like?


Adult beetles are:

  • About 1/2 to 3/4 inch long
  • Black with yellow bands across the wings
  • Reddish-orange head and thorax
  • Long antennae
  • Wasp-like in appearance

Larvae are:

  • Cream-colored
  • Legless
  • Wood-boring grubs


Signs & Symptoms of Infestation


Common indicators include:

  • Round exit holes in bark
  • Sawdust-like frass
  • Wood tunnels beneath the bark
  • Branch dieback
  • Declining tree vigor
  • Increased woodpecker activity
  • Structural weakening in dead wood

Most damage occurs inside the wood where larvae develop.


How Do They Damage Trees?


Adult females lay eggs in bark crevices or wounds.

After hatching, larvae:

  • Tunnel into wood
  • Feed beneath the bark
  • Create galleries in sapwood
  • Weaken branches and trunks

Because they usually attack weakened trees, they are often considered secondary pests.


Why Trees Become Vulnerable


Redheaded Ash Borers are attracted to:

  • Drought-stressed trees
  • Storm-damaged trees
  • Recently cut firewood
  • Dead or dying branches
  • Construction injuries
  • Trees weakened by disease

Healthy trees are generally less susceptible.


Why Are They Important?


Redheaded Ash Borers can:

  • Accelerate decline in weakened trees
  • Reduce lumber quality
  • Create structural defects in wood
  • Contribute to branch failure

However, they also play a beneficial ecological role by helping decompose dead and declining trees.


Prevention Tips


  • Maintain proper tree health
  • Water during extended drought periods
  • Avoid damaging bark and roots
  • Remove dead or severely damaged limbs
  • Store firewood away from healthy trees
  • Monitor stressed trees regularly


Can Infested Trees Be Saved?


If the tree is otherwise healthy, light infestations may not cause serious long-term problems. Trees already suffering from drought, disease, or extensive damage are more likely to experience decline.


Why Early Detection Matters


The presence of Redheaded Ash Borers often indicates that a tree is already under stress. Identifying infestations early can help property owners address underlying tree health issues before significant decline occurs.


At CBM Tree Service, tree health assessments can help identify Redheaded Ash Borer activity, evaluate overall tree condition, and provide recommendations to help protect valuable trees throughout Texas. 

Cottonwood Borer

Understanding Cottonwood Borer


The Cottonwood Borer (Plectrodera scalator) is a large native longhorned beetle commonly found throughout Texas and much of the southern United States. It is best known for attacking cottonwood and poplar trees, where its larvae tunnel into roots and lower trunks.


Although adult beetles are striking in appearance, the greatest damage is caused by the larvae feeding inside the tree.


Common Trees Affected in Texas


  • Cottonwood
  • Eastern Cottonwood
  • Poplar
  • Hybrid Poplar
  • Occasionally Willow


What Do Cottonwood Borers Look Like?


Adult beetles are:

  • 1 to 1½ inches long
  • Black with ivory or cream-colored markings
  • Equipped with very long antennae
  • Active during late spring and summer

Larvae are:

  • Cream-colored
  • Legless
  • Cylindrical grubs
  • Found inside roots and lower trunks


Signs & Symptoms of Infestation


Common indicators include:

  • Round exit holes near the base of the tree
  • Sawdust-like frass around roots
  • Root damage
  • Reduced growth
  • Branch dieback
  • Canopy thinning
  • Tree decline
  • Increased susceptibility to drought stress

Young trees are often affected more severely than mature trees.


How Cottonwood Borers Damage Trees


Adult females lay eggs near the base of host trees.

After hatching, larvae:

  • Bore into roots and lower trunks
  • Feed on wood tissues
  • Create tunnels and galleries
  • Disrupt water and nutrient transport
  • Weaken structural stability

Heavy infestations can reduce tree vigor and increase the risk of decline.


Why Trees Become Vulnerable


Cottonwood Borers are attracted to:

  • Newly planted trees
  • Drought-stressed trees
  • Injured trees
  • Poorly maintained trees
  • Trees growing in harsh conditions

Healthy trees are generally better able to tolerate infestations.


Why Are Cottonwood Borers Important?


They can:

  • Damage roots and lower trunks
  • Slow tree growth
  • Reduce tree stability
  • Increase susceptibility to disease
  • Cause mortality in young trees

However, they are also a natural part of Texas ecosystems and help recycle weakened wood.


Prevention Tips


  • Maintain proper watering during drought
  • Avoid trunk and root injuries
  • Apply mulch around the root zone
  • Promote overall tree health
  • Monitor young cottonwoods regularly
  • Inspect for exit holes and frass near the base


Can Infested Trees Be Saved?


Many established trees can survive light infestations if they remain healthy. Young or severely stressed trees may experience significant decline if infestations become heavy.


Why Early Detection Matters


Cottonwood Borer larvae can remain inside a tree for several years before emerging as adults. Early detection can help reduce stress on valuable trees and prevent long-term structural damage.


At CBM Tree Service, tree health assessments can help identify Cottonwood Borer activity, evaluate tree condition, and provide recommendations to help protect cottonwoods and other landscape trees throughout Texas. 

Pine Sawyer Beetles

Understanding Pine Sawyer Beetles


Pine Sawyer Beetles are large longhorned beetles in the genus Monochamus that are commonly found in pine forests throughout Texas. They are best known for their extremely long antennae and their habit of laying eggs in weakened, dying, or recently dead pine trees.


Unlike some bark beetles that attack healthy trees, Pine Sawyer Beetles are generally considered secondary pests, meaning they usually infest trees that are already stressed or damaged.


Common Trees Affected in Texas


  • Loblolly Pine
  • Shortleaf Pine
  • Slash Pine
  • Longleaf Pine
  • Virginia Pine
  • Other pine species


What Do Pine Sawyer Beetles Look Like?


Adult beetles are:

  • Large, often ¾ to 1½ inches long
  • Gray, brown, or black with mottled patterns
  • Equipped with very long antennae
  • Active during spring and summer

Larvae are:

  • Cream-colored
  • Legless
  • Wood-boring grubs found beneath the bark and in wood


Signs & Symptoms of Infestation

Most infestations occur after a tree has already been weakened.


How Pine Sawyer Beetles Damage Trees


Adult females lay eggs in bark crevices.

After hatching, larvae:

  • Tunnel beneath the bark
  • Feed on wood tissues
  • Create galleries in sapwood
  • Weaken branches and trunks

Heavy infestations can reduce lumber quality and weaken tree structure.


Why Trees Become Vulnerable


Pine Sawyer Beetles are attracted to:

  • Drought-stressed trees
  • Storm-damaged pines
  • Fire-damaged trees
  • Lightning-struck trees
  • Recently cut logs
  • Dead or dying trees

Healthy pine trees are usually less attractive to these beetles.


Why Pine Sawyer Beetles Are Important


They can:

  • Accelerate decomposition of dead trees
  • Reduce timber value
  • Weaken damaged trees
  • Create structural defects in wood

They also play a beneficial ecological role by helping recycle dead wood in forest ecosystems.


Relationship to Pine Wilt Disease


In some regions, Pine Sawyer Beetles can carry the pinewood nematode, a microscopic organism that causes Pine Wilt Disease. The beetles may transport the nematode from infected trees to healthy pines during feeding.


Prevention Tips


  • Maintain tree health during drought
  • Remove severely damaged trees promptly

Asian Longhorned Beetle

Understanding Asian Longhorned Beetle


The Asian Longhorned Beetle (ALB) (Anoplophora glabripennis) is a highly destructive invasive insect that attacks and kills many species of hardwood trees. Native to China and Korea, it was accidentally introduced into North America through infested wood packing materials.


Unlike many native wood-boring beetles that primarily attack stressed or dying trees, Asian Longhorned Beetles can infest and kill otherwise healthy trees.


Common Trees Affected


  • Maple
  • Elm
  • Willow
  • Poplar
  • Birch
  • Ash
  • Sycamore
  • Horse Chestnut
  • Various hardwood species


What Does Asian Longhorned Beetle Look Like?


Adult beetles are:

  • Large, about 1 to 1½ inches long
  • Glossy black with white spots
  • Equipped with extremely long black-and-white banded antennae
  • Active during summer months

Larvae are:

  • Cream-colored
  • Legless
  • Found deep inside trunks and branches


Signs & Symptoms of Infestation


Common indicators include:

  • Perfectly round exit holes
  • Sawdust-like frass accumulating on branches or at the tree base
  • Sap leaking from wounds
  • Branch dieback
  • Yellowing leaves
  • Canopy thinning
  • Structural weakening
  • Large internal tunnels

Infestations may go unnoticed for years because most of the damage occurs inside the tree.


How Asian Longhorned Beetles Damage Trees


Adult females chew pits into the bark and lay eggs.

After hatching, larvae:

  • Tunnel through the wood
  • Feed deep within trunks and branches
  • Disrupt water and nutrient movement
  • Weaken structural integrity

Repeated attacks eventually kill the tree.


Why Is Asian Longhorned Beetle Dangerous?


Asian Longhorned Beetles can:

  • Kill healthy hardwood trees
  • Spread rapidly through urban forests
  • Damage parks and landscapes
  • Reduce property values
  • Increase tree removal costs
  • Threaten native ecosystems

Because many tree species are susceptible, the beetle poses a significant environmental and economic threat.


What Are the Most Recognizable Signs?


Look for:

  • Round exit holes about ⅜ inch wide
  • Coarse sawdust around the trunk
  • Sap oozing from egg-laying sites
  • Large beetles with white spots and long antennae

These signs should be reported immediately if found.


Prevention Tips


  • Do not transport firewood long distances
  • Inspect hardwood trees regularly
  • Report suspicious beetles to authorities
  • Avoid moving untreated wood materials
  • Monitor for exit holes and frass
  • Maintain overall tree health


Can Infested Trees Be Saved?


Unfortunately, heavily infested trees are usually removed to prevent the beetle from spreading. Early detection is critical because infestations can expand quickly if left unchecked.


Why Early Detection Matters


Asian Longhorned Beetle infestations can remain hidden for years before symptoms become obvious. Detecting the beetle early can help prevent widespread tree loss and protect valuable urban and natural forests.


At CBM Tree Service, tree health assessments can help identify signs of invasive wood-boring insects, evaluate tree condition, and provide recommendations to help protect valuable trees throughout Texas.

The Three Types of Dung Beetles: Rollers, Tunnelers, and Dwellers

Dung beetles are commonly grouped into three behavioral categories based on how they use animal manure. Each group plays an important role in recycling nutrients, improving soil health, and reducing flies and parasites in Texas pastures and natural ecosystems.

1. Rollers (Telecoprids)

What They Do:
Rollers cut off a portion of fresh dung and shape it into a ball. They then roll the ball away from the original manure pile to bury it in the soil for food or as a nesting site for their larvae.

Key Characteristics:

  • Roll dung balls away from the source.
  • Bury dung underground for reproduction.
  • Often seen pushing balls several times their own size.
  • Help spread nutrients across the landscape.

Benefits:

  • Reduce manure buildup.
  • Improve soil aeration.
  • Increase water infiltration.
  • Lower fly breeding sites.
  • Help control livestock parasites.

2. Tunnelers (Paracoprids)

What They Do:
Tunnelers dig tunnels directly beneath a fresh manure pile and pull pieces of dung into underground chambers, where they feed and lay eggs.

Key Characteristics:

  • Dig vertical tunnels beneath dung.
  • Store manure in underground brood chambers.
  • Quickly bury large amounts of dung.
  • Excellent soil excavators.

Benefits:

  • Improve soil structure.
