62.029 Phycita roborella (Dotted Oak Knot-horn)
ws: 24-29mm; Jul-Aug; oak (Quercus spp); common in oak woodland in England
Phycita roborella §1 female
ID: According to Goater: "easily recognised by the reddish admixture of the forewing, together with the broadly triangular dark patch before the first line". These features are discernable in specimen §1; however, this species is variable in the extent of both pinkish grey and dark fuscous irroration of the forewing. Several other Phycitine species are predominantly reddish and the dark patch referred to seems to be neither consistently dark or triangular. The male antenna is strongly sinuate at base with a prominent tuft of scales.
