Species Overview:
Adult: 16-21 mm wingspan; forewings ochreous-cream apically, sometimes faintly tinged with salmon-pink, the remainder marbled with blackish to bluish grey and brownish grey.
Larva: 16-18 mm long; head, prothoracic plate and thoracic legs dark brown to black, plate edged with green anteriorly; abdomen dark green to olive-green, with a faint yellowish green or greyish green dorsal line; pinacula paler than integument but with black centres and bearing black setae; anal plate varying from green to brown or black [Hedya ochroleucana larva ].
Pupa: dull black; in the larval habitation.
Taxonomic Description:
Male:
Hedya ochroleucana adult 1
Hedya ochroleucana adult 2
Hedya ochroleucana adult 3
External characters: 16-21 mm wingspan. Forewing ground colour ochreous-cream, sometimes faintly tinged with salmon-pink, heavily overlaid with plumbeous and black strigulation between basal patch and median fascia; markings brown, strigulated with black intermixed with plumbeous; basal and sub-basal fasciae confluent; median fascia with outer edge slightly convex, extending obliquely to tornal area; a strong concentration of blackish and plumbeous medially; two or more black dots in medio-distal area; subterminal fascia obsolescent, reduced to a pale greyish or olive-ochreous suffusion; cilia ochreous-cream, suffused with grey from apex to before tornus, with a dark grey sub-basal line. Hindwing light grey, slightly darker apically and along termen; cilia paler, with a darker sub-basal line (Bradley et al., 1979).
male genitalia H. ochroleucana
Genitalia: Valva elongated, with tufts of setae along ventral margin. Aedeagus without cornuti. Uncus broad, apex bifurcate. Socii narrow.
Female:
External characters: Forewing colouration and markings similar to those of male; hindwing dark grey.
female gen. H. ochroleucana
Genitalia: Sterigma relatively small, strongly expanding anteriorly. Antrum elongated, expanding medially. Corpus bursae with two small signa.
Variation:
The intensity of the general colouration and markings may vary slightly. In fresh specimens, the salmon-pink flush is more pronounced.
Biology:
Moths fly in June and July. Larvae occur from April to mid June, spinning the leaves of the host plant into a large bunch. Pupation occurs in May and June, in the larval habitation.
Host plants:
Rosa; occasionally also on Malus.
Damage:
Larvae of this species are sometimes found on cultivated bushes of Rosa, spinning the leaves into a large bunch. They are also occasionally found on apple, but are of no economic importance on this host.
Distribution:
Europe to Eastern Russia, China, North Korea and Japan; North America.
Pheromone:
Pheromone unknown.
