Species details

Orthonevra brevicornis (Loew, 1843)


The larva is aquatic, living in accumulations of decaying vegetation, especially in mesotrophic or base-rich seepages in fens, meadows and occasionally woods. Adults can be found in marshes and fens.


This scarce species is widely distributed in England, though possibly more frequent towards the south and east. There are scattered records from both Scotland and Wales.


Was listed as "Notable" by Falk, 1991, but dropped from this status by Ball & Morris, 2010 who consider it LOWER RISK.
