Beris

Keith Bayless
Containing group: Beridinae

Introduction

Beris are 5-9 mm long and most species have a metallic green to blue thorax. The genus is Holarctic in distribution, with some species in Southeast Asia.  Adults of Beris in North America have been collected near streams and lakes, resting on vegetation (Woodley 1995). Larval Beris are found in moist leaf litter and decaying vegetation. The larvae of Beris clavipes and B. vallata live in moss (Rozkošný 1998). The habits of adults and larvae of European Beris species are summarized in Rozkošný (1982).

Characteristics

Beris is distinguished from all other genera in the subfamily by the reduced, one-segmented palpus (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.
