Spilonota laricana
Larch-bud Moth

(Heinemann, 1863)1205a / 49.225

Morley’s Final Catalogue: Probably distinct from the last kind, and a much rarer form. Not noticed with us since 1890, when it had been taken at only Flixton near Bungay (Ctw); and was sometimes found freely among larches round Brandon (Barrett, Tr. Norf. Soc. i, 54).

Recent Status: Scarcely recorded in Suffolk but has localised colonies.

Life Style: The moth is single brooded flying from June to August. The larvae feed on Larix decidua and sometimes on Picea sitchensis. They pupate in the larval habitation. The larvae hibernate. They initially mine a leaf. In spring they bore into a terminal bud.

Identification: There is a basal patch, roughly triangular pre-ocellar mark and termen, all marked dark. The ocellus is extensively black dashed and suffused grey. There is a dark suffusion from the costa at one half. The moth is similar to S. ocellana. S. laricana has a more irregular edge to the basal patch, more extensive grey suffusion in the costal half and ocellus, the black dashes in the ocellus are more extensive and the costal suffusion at one half more prominent. When dark forms of S. ocellana occur the paler areas of the wing are all darkened where-as S. laricana retains the pale dorsal central area. Identification by genitalia dissection is possible, but not easy, for the males but not possible for the females.
