Coleophora flavipennella

Description

Coleophora flavipennella is a moth of the family Coleophoridae. It was described by Philogène Auguste Joseph Duponchel in 1843 and is found in Europe. The wingspan is 11–13 mm. The forewing is plain yellow-brown. The ntenna white ringed fuscous from base to beyond half length of flagellum'Only reliably identified by dissection and microscopic examination of the genitalia. The moth flies from July to August depending on the location. The larvae feed on Castanea sativa, Quercus pedunculiflora, Quercus petraea, Quercus robur and Quercus rubra. Young larvae make a tiny blotch mine and then create a leaf case from the mined leaf fragment. Later this first case is enlarged with silk. The small leaf fragment remains part of the case. The final case is a light brown, trivalved, tubular silken case of about 7 mm with a mouth angle of about 45°. Full-grown larvae can be found in May.
