Thorny Devil

thorny devil

This stick insect is heavily armored, sports sharp body spines, and during the day clusters in groups for protection from predators. When disturbed, the males painfully clamp down with the especially large spines on their powerful hind legs and release a skunk-like odor.

Taxi-cab Beetle

This variegated yellow-trimmed beetle often feeds in groups, and perhaps then does look like a fleet of taxicabs jockeying for position. Eggs hatch into pale soft-bodied grubs that feed in compost and dung, and then pupate inside small earthen cocoons. The taxicab and yellow-bellied beetle belong to the same genus.

Sunburst Diving Beetle

This pretty beetle swims in groups and is brightly colored to advertise bad taste. It is streamlined, has powerful oar-like hind legs for propulsion, and steers with its short forelegs. Like many aquatic insects, it carries surface air beneath its wings to breathe under water. It can also fly!

Red-Eyed Assassin Bug

red eyed assassin bug

Assassin bugs have piercing-sucking mouthparts used to impale prey or enemies and
inject venom. The red eye-like spots on this insect’s wings serve to warn enemies of its
painful bite.

Jade-headed Buffalo Beetle

This beautiful beetle is attracted to fermenting fruit and often feeds in groups. The male has a small forked horn used to push rivals away from food and mates. The female is a bit smaller and hornless. Eggs are laid in the ground and the white, soft-bodied grubs, or larvae, burrow and feed in rotten wood and other detritus.

Hissing Cockroach


A loud hiss is enough to frighten away most predators. When disturbed, this fascinating roach hisses by forcibly expelling air from the spiracles or breathing pores on its first abdominal segment. Unlike many roaches, it is flightless and crawls rather than runs. The female gives live birth to many young.

Grey Bird Grasshopper

This grasshopper is a powerful jumper, strong flier, and camouflaged to blend with the ground at rest. It also is a prolific breeder and distantly related to the African migratory ‘locusts’ that sometimes form large destructive swarms. No wonder it has been so successful in our bird-eat-bug world!

Green-leaf Cockroach


This little green roach is camouflaged to look like a small-lobed plant leaf. It is a strong flier and fast runner, and is thus, difficult for predators to catch.

Giant Water Bug

Daddy does the babysitting! After the female lays eggs on the male’s back, it is then his job to clean and aerate the eggs, and carry them to safety when threatened. This insect breathes at the surface or from an air bubble held under its wings when submerged, somewhat like a tiny SCUBA diver.

Giant Walking Stick

The giant walking stick is one of the longest walking sticks. The adult female, with outstretched forelegs, spans over 15 inches! Worldwide, there are more than 2,500 closely related species, though some look more like leaves than sticks. Almost all use camouflage to fool insect-eating predators.
