About this speciesRecorded altitude range
0m to 175m
T. atrica occurs very sporadically in Britain. The species is widespread across the whole of continental Europe (Maurer 1992) and is common in Eire, but not Northern Ireland (Oxford & Chesney 1994). This curious Distribution: is probably a result of historical human importation into Eire from continental Europe.
Habitat and ecology
The habitat and ecology of this species seems to be identical to that of T. gigantea (q.v.). Where T. atrica occurs with T. saeva, apparent hybrids have been reported e.g. in Iceland where both species are frequently found in warehouses (Agnarsson 1996).
Older records probably refer to T. saeva/gigantea. In Britain, specimens are often found in locations such as garden centres and post offices, which suggest recent importation from Ireland or the continent. Self-sustaining populations have probably not established here.
