Containing group: Beridinae


Species of Actina are generally dark in coloration and have metallic green thoraces. They are found in most of the northern temperate regions of the world, including Canada, U.S.A. east of the Rocky Mountains, Europe, Mongolia, and parts of East Asia. The Asian species are predominantly found in mountainous habitats (Woodley 1995). Very little is known about the biology of these flies even though some species are common. Males of A. viridis form swarms. Larvae have been collected in sandy soil and in moss mats (Woodley 1995).


Actina is best distinguished from other Beridinae by the distinctive shape of the male gonostylus (Woodley 1995).

This page is a Tree of Life Branch Page.

Each ToL branch page provides a synopsis of the characteristics of a group of organisms representing a branch of the Tree of Life. The major distinction between a branch and a leaf of the Tree of Life is that each branch can be further subdivided into descendent branches, that is, subgroups representing distinct genetic lineages.

For a more detailed explanation of the different ToL page types, have a look at the Structure of the Tree of Life page.
