Subfamily Melolonthinae - Chafer Beetles

Family Scarabaeidae

This page contains information and pictures about Chafer Beetles in Subfamily Melolonthinae that we found in the Brisbane area, Queensland, Australia.

Beetles in this subfamily usually brown in colour, but may be black, metallic or bicoloured. They are commonly known as Chafers or Cockchafers. Male and female look no different. 
Their life cycle is usually more than one year. Larvae are long life, in C-shaped and soil-dwelling, feed on roots and other organic matter. They pupate in cell deep in soil. When become adults, they stay remains in the cell, wait until rain softens the soil and come out. This makes the adults come out from soil in the same time, synchronizes as the mating flight. Most of them active at night but some feed during the day. Adults live only a few days or weeks.
