Species text

B. trifrons has a widespread but patchy Distribution: in East Anglia, Wales, northern England and Scotland, but is very scattered or absent in most of central and southern England. The species is widespread in western and central Europe.

Habitat and ecology
B trifrons is most frequently found in wet habitats, such as fens, marshes and swamps, even garden ponds in the north. In upland and western areas it may be found in tussocks of grass such as tufted hair-grass, Deschampsia cespitosa, in damp but not especially wet habitats. Another habitat is sand dunes, where it occurs at the base of marram grass, Ammophila arenaria. Adult males occur from April to July, adult females from April to October, with a peak in June and July.

The species is scarce in the south, though common at Wicken Fen (Locket and Millidge 1953). It is more common in the north, but local.
