Caecidotea communis (Say, 1818)

Synonyms

Asellus communis (Say, 1818)

Status

GB IUCN status: Not applicable (non-native)
GB rarity status: Naturalised

Identification

This is generally a larger species with a looser, more ‘floppy’, appearance than Asellus aquaticus or Proasellus meridianus (Harding and Collis, 2006).

Distribution and Habitat

It is introduced from North America and is only known from Bolam Lake in Northumberland, where it appears to occur at the exclusion of the typically ubiquitous Asellus aquaticus.

It generally occurs in clear water with a substrate of mud or fine gravel and large quantities of decaying leaves from trees and shrubs.
