A general term for insects of the family Encyrtidae in the order Hymenoptera. Small parasitic wasps with a body length of about 1-2 mm. Many have a broad, hemispherical head and short antennae with 8-12 segments. They have large spurs on the tibiae of their middle legs, which they use to jump, hence the name Encyrtidae. They are distributed widely around the world and there are many species, with over 120 species in Japan. They mainly parasitize scale insects and psyllids, but some are known to parasitize moth larvae, ladybug larvae, and fly flies. Source: Heibonsha World Encyclopedia, 2nd Edition Information |
