Argyresthia retinella

These moths can be found in Europe,[1] across the Palearctic to Japan and Ussuri.[2] They are very common in the British Isles compared to other moth species.

This species is present in deciduous forest environments where birch grows.

Mounted specimen

Argyresthia retinella has a wingspan of 9–10 mm. Forewings are white with subtle greyish or light brown markings, with a darker drawing on the wing tip. Hind wings are gray.[3]

This species is rather similar to Argyresthia thuiella and Argyresthia fundella.

Argyresthia retinella is a univoltine species. Adults are on the wing from June to July depending on the location. Eggs of these moths were found almost exclusively on lichens. The larvae feed on the catkins and shoots of birch (Betula species).[3]
