 - Bugs on Milkweed plant seedpod
-
- This family can be distinguished from the Miridae
and Coreidae by their forewings which have 4-5 veins
and mostly ocelli absent. The front section of their forewings is
slightly harden and the back section membranous. Their hind wings are always
membranous. They are
usually brown to red in colour. Adults are from 4 to 20mm long, with oval shape and flattened
body. Their antennae are four segmented.
-
- Most species feed on plant seeds. Some are predaceous. They sometimes present
in great numbers.
