Classification

Subfamily:Coleophorinae
Genus:Augasma
Species:aeratella
Authority:(Zeller, 1839)

Formerly considered extinct in the British Isles, found on farmland, woodland margins and cornfield edges in southern and south-eastern England, from Dorset to Essex, in Norfolk and in Oxfordshire (MBGBI Vol 3): it was therefore welcome that it was re-found (or found to have re-colonised) sites in Wiltshire in 2023. In our area, there is a (possibly unconfirmable) single record from the Isle of Wight in 1907, but never recorded from Hampshire. Wingspan 9-10 mm. Distinguished from the Coleophora by the antennae, which are held tight against the body, not extending forward. Larva feeds within flowers of Knotgrass, forming galls, in which it over-winters.
