Morley’s Final Catalogue: Local on oak and perhaps sallow. Observed with us at only Copdock (Hkg), Bentley 1935 bred, and Barton Mills in 1934.
Recent Status: There are few Suffolk records.
Life Style: A single brooded species that flies during June and July. The larvae feed on Quercus species. After hibernation they feed from the edge of young leaves. They pupate on a leaf or twig.
Identification: There are seven members of the albidella group of Coleophora of which six are very similar and difficult to identify. C. anatipennella, C. albidella, C. kuehnella, C. ibipennella, C. betulella and C. currucipennella all have white forewings, thorax and head and a prominent white scale tuft on the antennal scape. There are minor differences in wing colour. The genitalia are all very similar and they all, except for C. kuehnella, have similar pistol shaped cases. However they have different foodplants. The larvae, having initially mined a leaf, become grazers of leaves from their mobile case. C. kuehnella is the largest species of the albidella group. It may have scattered black or dark fuscous scales on the veins towards the apex and has a narrow dark costa base. More Info
