Heteropteryx dilatata

English

Description

These large, spiny insects with their long antennae are very impressive! The males and females look quite different. The females, which can reach 16 cm in length and weigh up to 50 g, are armed with several spines of different lengths. While the females are generally leaf green, the males are brownish. The males are about 9 cm long and have large purple wings enabling them to fly short distances.

Their name comes from the fact that the females’ brachypterous wings make them look like nymphs.

Extatosoma tiaratum

English

Description

When it first emerges from the egg, a giant prickly stick insect resembles a large brownish-red ant. The adults are sandy brown with flattened, leaf-shape legs. Males are 10 cm long with slender bodies. Females are 10 to 16 cm long with wider bodies. Males’ wings are more developed than females’. Males have only four spines on their backs, while females have two rows of spines.

Eurycantha calcarata

English

Description

Giant spiny stick insects are large chocolate-brown insects with sturdy, very spiny bodies. The males average 11 cm long, and the females 13 cm. Both sexes have very thick carapaces. The males have strong femurs with large spines. The females are spineless, and have well-developed ovipositors (egg-laying organs).

Eleodes sp.

English

Description

Darkling beetles are small and black, but on close examination their shells reveal a wide variety of shapes and textures. This makes them just as interesting to look at as other, more colourful beetles. Darkling beetles are 3 to 4 cm long.

Dynastes hercules

English

Description

Like most scarab beetles, the two sexes are easy to tell apart (sexually dimorphic), particularly because of the males’ horns. The males may be 50 to 175 mm long, with two pincer-like horns in front. The elytra (wing covers) are pale greenish-yellow, with widely spaced, irregular black spots and a black border.

The females are 50 to 70 mm long, with a dark brown body covered in reddish-brown fuzz. They do not have horns.

Acheta domesticus

English

Description

Along with locusts and grasshoppers, crickets belong to the leaping insect family. They have short, strong hind legs. The antennae are long and slender. They have two sensory filaments, called cerci, at the tip of their abdomens. Females have a long egg-laying organ, called an ovipositor, between these two sensory organs. House crickets are over 13 mm long.
