Knobbled Weevil

A large, knobbled weevil endemic to New Zealand, covered in rough tubercles that give it a bark-like appearance. It is nocturnal and flightless, found in native forests. Its rough texture provides excellent camouflage against tree bark.

💡

Did You Know?

When disturbed, the knobbled weevil plays dead and drops to the ground, where its bark-like texture makes it nearly invisible among leaf litter.

A striking metallic green stag beetle from South American cloud forests. Males have elongated mandibles with tooth-like projections.

💡

Did You Know?
