Early stages:
Swatschek, 1958, provides a diagnosis for the larvae of over 20 species of 'Olethreutes'' (in fact larvae of several genera such as Hedya, Celypha, Pseudosciaphila, Olethreutes, Phiaris, Argyroploce, Apotomis, Stictea, Pseudohermenias, Eudemis and Orthotaenia).
Crochets on abdominal prolegs biordinal; D1 and SD1 on separate pinacula on A9, or SV group bisetose on A7. Sutura coronalis significantly longer than greatest width of adfrontals, or L1 and L2 more or less equal in length.
Biology:
One generation yearly; larvae feed on conifers (Pinus, Abies, Picea).
Distribution:
Palaearctic Region.
