Argyresthia semitestacella (Curtis, 1833)

Wingspan: 11-14mm

A univoltine species recognisable by its large size and appearance late in the year. On the wing in August and September it is a scarce visitor to light but can be disturbed from beech trees. Recorded at Las Descargues and from the beech woodland at Latronquière.

Larva feeds on the shoots of beech Fagus sylvatica.
