Darkling Beetles - Family Tenebrionidae

This page contains information and pictures about Darkling Beetles that we found in the Brisbane area, Queensland, Australia.
 
 
Beetles in this family are medium in size. They are usually black or brown in colour. Some are dark blue or green with metallic reflection. They are highly variable in shape and with concealed antennal insertions. Their antenna are medium length, stout, either moniliform (antenna in which the antennomeres are about as long as wide and more or less bead-like) or incrassate (antenna in which the antennomeres gradually increase in width towards the apex ). Their legs are relatively long.
 
Adults feed on variety of decaying materials of plants, lichens or fungal. Many occur under rocks and in leaf litter.
