Bugs with human looking faces can seem strange or even disturbing to many people. However, these insects are simply exhibiting adaptive traits that have evolved over time. In this article, we will explore some of the most well-known bugs with humanesque facial features, the reasons behind their peculiar appearances, and whether they pose any threat.
Insects with human-like faces
Several types of bugs have facial characteristics that resemble a human’s in surprising ways. Here are a few examples:
Thorn bug
The thorn bug (Umbonia crassicornis), found in Central and South America, is aptly named for the thorn-like projections on its head and thorax that give it a spiky appearance. When viewed head-on, its eyes, mouth parts, and antennae bear an uncanny resemblance to a human face.
Atlas beetle
The male atlas beetle (Chalcosoma atlas), native to the Southeast Asian tropics, boasts an elongated head and antennae that can look like an old man’s beard and mustache from certain angles. Its eyes and rounded mouthparts also lend it a humanoid visage.
numbats
Numbat moths (Nycteola species), found in North America and Eurasia, have coloration resembling large eyes near their heads and dark furry scales along the sides of their bodies that can appear like human hair or beards.
buffalo treehopper
The buffalo treehopper (Stictocephala bisonia), common in North American grasslands and forests, has a pronounced hump on its back along with eyes, antennae, and mouthparts arranged to look like a tiny human face.
camel crickets
Camel crickets, also known as cave crickets (Rhaphidophoridae family), widespread in temperate regions, have a rounded body segment right behind their heads that gives the appearance of a human-like face with large eyes and a wide mouth.
Reasons for the human-like features
There are a few possible evolutionary explanations for these humanesque visages:
Mimicry
Some species may gain an advantage through mimicry of human or other vertebrate facial characteristics that help them evade predators who find such features unpleasant or alarming.
Sexual selection
Elaborate facial structures like a male atlas beetle’s projections could arise through sexual selection, giving them an edge in attracting mates.
Coincidence
In many cases, the human-like appearance is simply coincidental and not adaptive at all. The specific arrangement of eyes, mouthparts, and other facial features may just superficially resemble a human face.
Pareidolia
Some human-like visages in the insect world are subjective cases of pareidolia – the tendency for human perception to see meaningful shapes or patterns where none were intended. Much depends on the angle viewed.
Are these bugs dangerous?
For the most part, insects with humanesque faces are harmless to humans. For example:
- Thorn bugs eat plants and pose no risks.
- Atlas beetles are not toxic or aggressive.
- Numbat moths cannot bite or sting.
- Buffalo treehoppers mainly feed on plants and trees.
- Camel crickets are omnivorous scavengers but harmless.
Some exceptions where caution is warranted include:
- Wheel bugs can inflict a painful bite with toxic saliva.
- Giant water bugs will bite if handled and have a painful enzymatic bite.
- Some giant horned beetles can pinch painfully if threatened.
In general though, any threats from human-faced arthropods are minor, and most should be appreciated for their fascinating features that have evolved over millennia.

Conclusion
While the human-like facial features exhibited by some insects may seem bizarre or unsettling, they represent the amazing diversity and adaptation found in nature. Understanding why and how these traits evolved can provide insight into insect ecology and biology. In most cases, human-faced bugs are harmless curiosities that play important roles in their environments.
