37.005 Coleophora lutipennella (Common Oak Case-bearer)
ws10-12mm; Jul-Aug; deciduous oak (Quercus spp); common in oak woodland in England & Wales
Coleophora lutipennella §4 female
ID: Forewing without longitudinal streaks or white markings; not metallic; antenna white, ringed fuscous throughout, proximal segments not thickened; forewing not grey and without stigma. If it is possible to determine that the forewing is ochreous-orange rather than ochreous-brown (as in the key in MBGBI3) then > C.flavipennella/lutipennella. I suspect this distinction will not usually be reliable so > 13 species which require genital dissection to determine.
Male genitalia: very distinctive in having a very large aedeagus; sacculi almost entirely separated from the valvae; sacculae with multiple spines on the ventral surface and a short apical point.
Female genitalia: Signum moderate, spike longer than width of base plate; introitus vaginae broad, sclerotised and extending much further than length of subgenital plate beyond the subgenital plate, narrowing at junction with ductus bursae.
