Papilla analis flattened, with numerous hairs; anterior portion narrow and weakly bending inwards. Sterigma fused with seventh abdominal sternite, subtriangular or trapiziform, caudal margin with a median emargination or notch. Ostial opening oval; ductus bursae well-sclerotized, except for a short membranous posterior portion; corpus bursae round, with a pair of short, curved, pointed signa.
Early stages:
Swatschek, 1958, provides the following diagnosis for the larvae based on chaetotaxy of Spilonota ocellana :
SV group trisetose on first and second abdominal segments, bisetose on seventh, eighth and ninth; both D2 seta, as well as setae D1 and SD1 on shared pinacula on ninth abdominal segment. V setae further apart on ninth abdominal segment than on eighth. L1, L2 and L3 set in a diagonal line on prothorax.
Biology:
One to two generations yearly; hibernation in larval stage; larvae feed on a variety of plants belonging to different plant families.
Distribution:
Palaearctic, Nearctic and Oriental regions.
