True Crickets - Family GRYLLIDAE

This page contains pictures and information about True Crickets in Family GRYLLIDAE that we found in the Brisbane area, Queensland, Australia.
The True Crickets can be distinguished from other crickets by presence of long ovipositor and long cerci in females. They have very long antenna. Their body is usually slightly flattened. 
They are nocturnally active. They live on the ground. They may be found in burrows, crack in soil or amongst leaf litter. Males produce complex love songs by rubbing wings together. Their hearing organs are on the front legs.
