The flower bugs resemble the Miridae in possessing a cuneus (an area on the forewing differentiated by the costal fracture), but differ by possessing ocelli and lacking veins in the forewing membrane.

The anthocorids are usually small, inconspicuous predators that feed mostly on small arthropods or insect eggs. Some overseas species are known to include pollen in their diet. Anthocoridae occupy a wide range of habitats including flowers, under bark, in caves and leaf litter, as well as stored agricultural products where they prey on pests.

Most Anthocoridae practice an unusual method of reproductive behaviour called traumatic insemination. The male deposits the sperm inside the female by piercing the external body wall of the female. The sperm then accumulates inside the body cavity in an organ called the spermalege from where the sperm transfers to the genital tract.


Three subfamiles and 28 species of Anthocorids are represented in Australia. The subfamily Anthocorinae contains the majority of the fauna with 11 genera and 22 species. The Lasiochilinae, concentrated in the eastern and northern areas of the Australian mainland, contains 4 genera and 5 species. The Lyctocorinae, the smallest subfamily, contains only the introduced species, Lyctocoris campestris .
