Mirid Bugs - Family Miridae

Mirid Bugs are common in Australia, the largest family of the Heteroptera. However, we do not have many photos and information on them for most of them are very small, 2-6mm in body length, and well camouflaged.
 
 
Some bugs in this family feed on plants only while many others feed on small soft body insects and insect eggs. Some species feed on both. They are usually yellow, green brown or black in colours, though some are colourful. Some are ant mimics.
