A consultant to the Beetles of Australia is an interesting creation to this large and numerous crew of bugs – the Coleoptera. Beetles make up forty% of all bugs. The variety of identified beetle species on this planet – greater than 350,000 – is greater than six occasions the variety of all vertebrate species.

New beetle species are being stumbled on forever. Of the 30,000 species which may ensue in Australia, purely 20,000 were scientifically defined. those comprise round 6,000 weevils (Curculionidae), 3,000 scarabs, dung beetles and chafers (Scarabaeidae) and 3,000 leaf beetles (Chrysomelidae).

A advisor to the Beetles of Australia highlights the big variety of this precise insect Order. It emphasizes the environmental function of beetles, their relationships with different crops and animals and their significance to humans.

These beetles obtain their food in a more or less similar manner to myrmecophiles. This ferocious aquatic beetle, a predatory dytiscid, can ambush an equally fearsome, predaceous water scorpion and make a meal of it. 32 FOOD AND SUR VIVAL One of the largest termite-loving beetles in Australia is the 6-mm-long Megaxenus termitophilus (Aderidae), which is often seen on the outside of termite mounds in north Queensland rainforests. This weevil (Curculionidae) is using the chewing mandibles at the tip of its rostrum to dig holes for its eggs.

Beetles of the temperate zones may pupate at the end of summer, survive the winter as pupae and the adults emerge only next year at spring or summer. Tropical species may develop quicker, but still could spend months as pupae. When the adult beetle – also known as the imago – emerges from the pupa, the process of change is just about complete. The freshly emerged imagos of some species may be a little soft and even colourless for a short while but their exoskeletons darken and harden rapidly. Others, like some ladybirds (Coccinellidae), may take several months to acquire their full colour.

They differ from the preceeding suborders by having rigidly fixed coxae and six abdominal ventrites. Superfamily Caraboidea The most distinctive feature of these beetles is that their first abdominal segment is divided by the hind coxae. Their antennae are usually thread-like, but sometimes beadlike, clubbed or even extraordinarily flattened (Carabidae: Paussini). Most beetles belonging to this superfamily are predaceous. Many of them are terrestrial, others are aquatic or semi-aquatic. ) Suborder Myxophaga Beetles belonging to this suborder are minute (usually less than 1 mm), with visible notopleural sutures on the prothorax and with short, clubbed antennae.
