Big-eyed Bugs - Family Geocoridae

This page contains pictures and information about Big-eyed Bugs in Family Geocoridae that we found in the Brisbane area, Queensland, Australia. 
 
Bugs in this family have separated and very big eyes. They are commonly called Big-eyed Bugs. They are small in size. They have either elongate, elongate-ovoid or oval body. They are seed feeders but also known to be predaceous. This group of geocorid bugs were put as the subfamily of the Lygaeidae. They are raised to family level in 1997.
