Mitchell's Diurnal Cockroach

A large, flightless cockroach with a shiny dark blue-black body found in arid Australia. Unlike most cockroaches, it is active during the day.

💡

Did You Know?

Its bold daytime activity is thought to be possible because its dark, hard body deters predators.

Arctic Tiger Moth

A striking moth with black and cream striped forewings and orange-red hindwings with black spots. The hairy caterpillar is black with reddish bands. Adults are active during the brief Arctic and alpine summer.

💡

Did You Know?

The caterpillar's dark coloration allows it to bask in the sun and raise its body temperature well above the ambient Arctic air temperature.
