Tree bark comes in a variety of colors textures and patterns. This provides the perfect opportunity for certain bugs to blend in as a form of camouflage and protection. Bugs with grey, brown, or black coloring can remarkably resemble the bark of trees, remaining undetected by predators. We’ll explore some of the most interesting bark-mimicking bugs and how their appearance helps them survive.
Masters of Disguise
There are over 200 species of underwing moths in the genus Catocala. Most have forewings in shades of grey, brown, or black – ideal for matching tree bark. When at rest, the hindwings are hidden, showing only the bark-like forewings. If threatened, the moths flash their bright yellow, orange, or red underwings to startle predators.
The common lytrosis moth inhabits eastern and southern parts of North America. Its mottled brown and grey wings and body provide camouflage against tree trunks. With a wingspan up to 2 inches it’s one of the largest North American moths.
The brown bark carpet moth lives in eastern North American gardens. As the name suggests its brown and grey forewings resemble bark and provide great coverage when resting on trees. Their caterpillars feed on flowers like garden clematis.
Hiding in Plain Sight
The mourning cloak butterfly has a surprising appearance. Viewed from above, it’s very dark brown, but the underside is grey, brown, and black – just like tree bark. When threatened, they open their camouflaged wings to avoid detection. Some can live up to one year by using this technique.
Geometer moth caterpillars are known for their unusual body postures and movement style. Many are twig-like with grey, brown, or green coloring to match the plants they eat. When alarmed, they stiffen into strange poses that resemble vegetation. Their name comes from the way they “measure the earth” as they move.
More Than Just Coloring
The aptly named bark crab spider hunts on tree trunks. Its grey and black abdomen, combined with a flattened body shape, hides it perfectly on rough bark. Instead of building webs, it ambushes prey like flies and bees.
Bark praying mantises use an array of strategies like flattened bodies and fringes that break up their outline. Coloring ranges from mottled greys to browns that mimic lichen-covered bark. Some species even mimic ants or thorns for added protection.
The Arizona bark scorpion is highly venomous. It spends its days sheltered under tree bark or other debris. Its brown or tan coloring provides camouflage against the desert landscape. Around 2.7 inches long, it’s one of the smallest scorpions.
The Advantages of Mimicry
Many other bugs like longhorn beetles, birch catkin bugs, and lichen moths use bark mimicry to avoid predators like birds, wasps, and parasitic insects. Their cryptic patterns and textures make detection very difficult. It’s an incredibly effective adaptation that helps many species thrive in their natural habitats.
The variety of colors, textures, and patterns in tree bark provides the perfect opportunity for concealment. Over time, many bugs have evolved remarkable camouflage that seamlessly blends with their surroundings. Their bark-like appearance is an ingenious strategy to avoid becoming someone’s next meal!
Where do bark beetles live?
They can be found across the United States, particularly in forests and wooded areas. You can also find them in neighborhood trees, city parks, or yards.
How to get rid of bark beetles
Once a tree has bark beetles, theres little that can be done to eliminate the bark beetles. However, prevention is the best course of action to keep bark beetles away.
Strategies to prevent bark beetles from infesting your trees include:
- Remove infested wood: To prevent spread, remove and destroy infested trees or limbs
- Keep trees healthy: Proper watering and care can make trees less inviting to beetles.
- Be careful with firewood: Dont transport firewood from other areas, as it can spread beetles.
- Reduce tree stress: Applying mulch can help retain soil moisture, and properly pruning can reduce tree stress.
If you have high-value trees that you really care about, applying a pesticide treatment on the tree directly can help, although you may risk killing beneficial insects that keep bark beetles in check.

FAQ
What is the bug that looks like a bark?
Bark beetles are distinct in their morphology due to their small size and cylindrical shape. Bark beetles also have small appendages, with antennae that can be folded into the body and large mandibles to aid in the excavation of woody tissue.
How are bark beetles harmful?
Elm bark beetles are pests because they feed in the phloem of elms and spread the fungus that causes Dutch elm disease.
What are the brown bugs that look like tree bark?
The bark beetles causing widespread mortality in the forests and forested communities in California are all native. The principal species include: mountain pine beetle, fir engraver beetle, western pine beetle, Jeffrey pine beetle and pine engraver beetles.
What does bark beetle infestation look like?
Signs of Bark Beetle Attack
Initial evidence of a beetle attacked tree includes: sawdust at the base of the tree or in crevices in the bark from the beetles boring into the tree, small popcorn like masses of sap (called “pitch tubes”), and small boring holes where beetles have entered the tree.
Which bugs look like tree bark?
Some bugs, also known as bark mimics, have evolved to look like tree bark in order to protect themselves from predators. As we walk through the woods or even in our own backyard, we may come across these interesting creatures that blend in perfectly with the bark of trees. One such bug is the webbing barklice.
Which insects live in tree bark?
Other insects, such as stick insects and moss bugs, live in tree bark to blend in and avoid detection by predators. The study of tree bark is a fascinating subject that reveals the intricacies of the natural world and highlights the importance of preserving our planet’s forests.
What insect looks like tree moss?
The insect that looks like tree moss is the moss bug. This insect belongs to the family Peloridiidae and has a flattened body shape that blends well with its environment, such as the bark of trees or mossy surfaces.
Do moss bugs look like tree bark?
Moss bugs, also known as the Peloridiidae family, resemble tree bark. They consist of eighteen genera and thirty-four species and are commonly found in forested areas. These bugs blend in with the bark of trees and are often difficult to spot.
What does a Brown Marmorated Stink Bug look like?
The Brown Marmorated Stink Bug has a dark gray to brown color that mimics tree bark. This makes the species difficult to spot when resting on trees or in dense vegetation.
How do you know if a tree has bark lice?
The presence of webbing and a colony of small insects may indicate a bark lice infestation. “Bark lice” is the common name for Psocoptera. They are small brown insects feeding on the debris found on the bark of trees and shrubs. Bark lice frequently appear on trees and shrubs with smooth bark, such as Crepe myrtle and oaks.
