Mirid Bugs - Family Miridae

This page contains pictures and information about Mirid Bugs in family Miridae that we found in the Brisbane area, Queensland, Australia.
Mirid Bugs in family Miridae are common in Australia. Miridae is the largest family of the Heteroptera. However, we did not find too many of them. Most of them are very small, 2-6mm in body length. Some are very well camouflaged.
The large size Mirid Bugs look similar to Lygaeid Bugs. They can be distinguished by there are usually one or two closed cells on wing membrane, thickened portion of front wing with a cuneus, a somewhat triangular shaped area adjacent to the membranous area. Most of them are ocelli absent except one subfamily. They are usually yellow, green brown or black in colours, al though some are colourful. Some are ants mimics and some are Parasite Wasps mimic. 
Most bugs in this family feed on plants while others on small soft body insects and insect eggs. Some species feed on both.
