Morley's Final Catalogue: Not listed

Recent Status: Originally an adventive species captured at light in Sussex during 2008 is now an established resident in that county.
It has since been found elsewhere in Great Britain and also in France and the Netherlands. Originally from Madeira.

The first Suffolk record was at light on 14 December 2021 in Felixstowe. More records followed in 2022. Expected to continue colonizing the county in future years.

Life Style: A double brooded species found in all but the coldest months of the year. The larvae are as yet unknown.

Identification: This is a very variable species of Blastobasis. It may appear unicolorous brown, grey or blackish or can appear well marked similar to B. adustella but seldom shows the ‘V' of the common Suffolk Blastobasis strongly. One form exists with a black streak from the base to the apex. The females are more contrastingly marked than the males. More Info It is the smallest of the Blastobasis species in Suffolk and requires genitalia dissection for confirmation of a record More Info

Verification Grade Comment: Most will require dissection to determine the record. The female moths, if they show the distinctive black shoulders, will be accepted as correct if a photo is sent in with the record.
