PNG Giant Katydid
A very large katydid found in the rainforests of Papua New Guinea, with a body resembling a green leaf. Its leaf mimicry is remarkably detailed, including simulated vein patterns, leaf edges, and even brown spots resembling fungal damage.
Did You Know?
This katydid's leaf mimicry extends to simulating insect damage and fungal spots on its wings, making it virtually invisible among real foliage.
Violet Longhorn
A compact, flat cerambycid with a striking metallic violet coloration across its entire body. Widespread in conifer forests of the Northern Hemisphere, it breeds in dry dead conifer wood. Adults are occasionally found in houses after emerging from firewood.
Did You Know?
Larvae can survive in kiln-dried timber and have emerged from furniture and log cabin walls years after construction.
