A general term for insects in the Hemiptera family Anthocoridae. They feed on other insects, insect eggs, and spider mites. They are so named because they sometimes live on flowers. They are extremely small and all insectivorous. There are about 500 species recorded worldwide, with about 30 recorded in Japan. The body is flat and slender, and the head protrudes significantly forward beyond the compound eyes. They have simple eyes. The antennae are four segments, with the two tip segments being thread-like and the base two segments being of similar thickness. The brown stink bug, Lyctocoris beneficus , is around 3.5 mm long.
