New Zealand Sand Scarab
A large flightless scarab beetle endemic to sandy coastal habitats in New Zealand. It is nocturnal and burrows in sand dunes during the day. Once common on beaches, it has become increasingly rare due to habitat modification and introduced predators.
Did You Know?
This beetle was once so common on beaches that Maori used it as fish bait, but predation by introduced rodents has severely reduced its numbers.
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.
