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.

Blue Metalmark

A tiny butterfly with vivid metallic blue upper wings that flash brilliantly in sunlight. It perches on rocks and gravel near streams in tropical forests.

💡

Did You Know?

Its brilliant blue iridescence is structural rather than pigmented, produced by nanoscale lattice structures in the wing scales.
