Wingspan c. 15mm
Very probably an imported species or accidental introduction, this nondescript species has occurred in recent years on Guernsey and more recently there have been a couple of wild-caught records in the north of England.
Other records are attributed to an outbreak from a plant nursery in Cornwall, and it has been found in glasshouses in other parts of Europe. In recent years it has become frequent on the Isles of Scilly, with good numbers recorded around the incinerator/dump area of St. Mary's.
The larvae of Omoscopa species tend to feed on decaying vegetation.
