Neoascia interrupta

Neoascia interrupta (Meigen, 1822)

Biology & ecology:

The larvae of this genus are associated with rotting vegetation and many are wholly aquatic. Field observations suggest that an association with Greater Reedmace Typha latifolia is possible, but the evidence is circumstantial. It would appear to be tolerant of brackish conditions and occurs extensively across the grazing marshes of the Thames estuary.


This species is almost entirely confined to eastern England as far north as South Yorkshire and west to Warwickshire and Oxfordshire. There are, however, reliable records from North Wales in 1987 and from Leighton Moss in 2008.

Status & conservation:

There do not appear to be changes in the frequency of recording.

Recorded from 86 hectads since 1990.
