Forewing costa gradually arced outwards; forewing ground colour whitish with a brownish hue, strigulated with brownish, especially in basal field. Markings pale yellowish-brown; basal patch ill-defined; median fascia brownish, from middle of costa to before tornus; a small black dot present near median fascia; 3 pale brownish-grey costal striae present before apex and some pale brownish-grey wavy lines from costa to tornus and especially termen. Cilia brownish-yellow, with brown sub-basal line. Hindwing with anal fold; somewhat darker brownish; cilia whitish with brown sub-basal line (Kennel, 1908-1921; Kuznetsov, 1987).
male genitalia A. lutosana
aedeagus & sacculus A. lutosana
Genitalia: Valva with monochromatic basal projection, narrow, with rounded process on sacculus; this process covered with group of close-set, thickened, pigmented spinescent setae. Cucullus narrow, clavate along ventral margin and covered with piliform bristles. Uncus narrow and thin. Socii large, broad, bent outwards, densely pilose. Aedeagus curved, vesica with one small cornutus.
Female:
External characters: Similar to male; hindwing without anal fold.
female gen. Apotomis lutosana
Genitalia: Sterigma expanding around ostium bursae, anterior angle convexely rounded. Ductus bursae swung, sclerotized posteriorly, ductus seminalis originating anterior to this sclerotized area. Two small scobinate concavities represent the signa.
Biology:
Moths fly in late July and August. Not much appears to be known about the biology of this species. Razowski, 1989, mentions, when discussing the genus Apotomis in general, that there is usually only one generation yearly, and that the larvae hibernate.
Host plants:
Oleaster (Eleaegnus), olive (Olea europaea).
Damage:
Larvae damage oleaster trees in parks, feeding between spun leaves of oleaster and skeletonizing them (Kuznetsov, 1987).
They are also recorded as a pest in olive orchards in Turkmenistan (Popescu-Gorj, 1984).
Distribution:
Romania, Trans-Caucasus, Caspian Steppes, Kazakhstan, Turkmenistan, Uzbekistan, Tadzhikistan (Kuznetsov, 1987).
Pheromone:
Pheromone unknown.
Parasitoids:
Nemorilla maculosa Meig. (Tachinidae) (Rikhter and Durdyev, 1988)
