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.
