Yorkshire Status: Uncommon and local resident.

Round-winged Muslin is probably the only Footman in the county whose numbers have fallen in recent years. It has never been a common moth in Yorkshire, and Porritt was only aware of records from Askham Bog, Scarborough and Wheatley Wood (Doncaster). It is a moth of damp places and is remarkably easy to confuse with Muslin Footman. Most of our records come from Spurn, but very good numbers still occur at Askham Bog, and Thorne and Hatfield Moors seem to support good populations. It is rather local in several other damp places in the county and sometimes wanders a mile or two to what would appear not to be ideal habitat. Most of the really big counts came from Spurn in the 1980s, the maximum being 97 on 18/7/1986. More recently, Askham Bog has provided many counts into the 20s and 30s.

Sutton & Beaumont, 1989: Appears to have spread considerably since the last list (YNU, 1970). However it has been suggested (PQW pers. comm.) that it is being confused with N. mundana (Linnaeus), since many sites are not marsh or fenland, the typical habitat for this species.
