Copidosoma floridanum

Because of its polyembryony it produces enormous quantity of DNA which facilitates DNA studies and it is used in genome sequencing.

Diversinervus elegans

Native to the Old World. Introduced into California during a biocontrol program directed against Saissetia oleae, starting in the 1950s.

Homalotylus hemipterinus

There are two UK species in this genus. In Homalotylus flaminius the hind tarsus is white, the clava either dark on the basal third and whitish on the distal two-thirds, or black with a paler tip Unless identified by a recognised expert, a photo is r
