There are around 30 different species of bess beetles in Australia, and about five occur in the Sydney area.
Bess beetles are commonly found in rotting logs, usually in a small colony made up of a number of adults and larvae.
Bess beetles are found in eastern Australia.
Feeding and diet
The adult bess beetles prepare the food for the larvae by chewing the wood into a soft pulp, which the larvae can eat.
Other behaviours and adaptations
Adults are commonly attracted to lights. When handled or threatened, bess beetles rub parts of their body together to produce a rasping sound. Most bess beetle species have tiny mites attached to them that are probably parasitic.
