Coccinea

Cottony cushion scale Icerya purchasi, from Clemson University.

Belongs within: Aphidomorpha.
Contains: Ortheziidae, Coccoidea, Matsucoccidae.

The Coccinea include the scale insects, a characteristic group of plant-sucking bugs in which the females have become larviform and generally immobile.

Characters (from Griamldi & Engel 2005, as Coccoidea): Sexual dimorphism extreme: females highly neotenic, larviform, lacking eyes and wings, antennae and legs also usually highly absent; first-instar crawler as dispersal stage. Males lacking mouthparts; hind pair of wings reduced, often to tiny knobs (hamulohalteres).
