Acleris umbrana

Range & Status

Listed by Ball (1986) as pRDB1, with few records from Gloucestershire, Cornwall, Devon and Herefordshire until the early 21st century, when both the number of records and its distribution increased (Heckford pers. comm.). Recorded from places throughout central Europe. Previous confusion with some forms of Acleris hastiana have cast doubt on some of the older records.

Regional Distribution

First recorded in Cornwall in a garden at Saltash (to light in 1971), but not recorded in Devon until 1992. In January 2006 one came to light at Downderry and four larvae were found at Seaton in August the same year (Heckford pers. comm.). In 2007 larvae were found at Rame Head and in 2008 further singles came to light at Downderry and at Torpoint.

Habitat & Ecology

According to Bradley, Tremewan & Smith (1973) a polyphagous species of deciduous woodland, but recently found on Blackthorn Prunus spinosa on coastal cliffs. The adult flies at night and during the day rests high in the foliage where it is rarely seen. Probably bivoltine, at least in Devon.
