Vulcaniella pomposella is a butterfly ( moth ) from the family of cosmopterigidae (Cosmopterigidae).

features

The moths reach a wingspan of 8 to 10 millimeters. The head shines dark brown and glitters gold. The antennae are dark brown and ringed white in the first three quarters. In the last quarter there are five white segments, each separated by three dark brown segments. The thorax and the tegulae shine dark brown and glitter golden. Both are lined with silvery scales at the rear end . The forewings shine dark brown and glitter golden. An outwardly sloping, raised, silvery band is located at 1/6 of the fore wing length and extends beyond the anal fold. The wing markings include six raised silver spots. Two are on the Costa loader . The first lies in front of half the wing length and the second at 3/4 of the forewing length together with a white line that extends from the Costa Lader to the fringed scales. There are three more spots on the inner edge of the wing. The first lies in front of the middle of the wing on the anal fold, the second on the inner edge of the wing between the two costal spots. The third is on the interior corner . There is a white spot at the apex . The fringed scales are dark brown and gray around the apex and at the base of the wing. The hind wings have a gray sheen and are more brownish at the apex. The abdomen is dorsally dark gray. The forewings of the females are clearly constricted in front of the apex, the abdomen is ocher-brown.

In the males, the right brachium is curved inward and sharply tapered distally . The apex is slightly widened. The left brachium is thickened in the middle and has a rounded apex. The blades are wider at the base, the distal half is straight. The right Valvella is as long as the Valven. It is slightly wider at the base and has a rounded tip. The basal part is ventrally bulbous. The left valvella is short and gradually tapers. The aedeagus is straight, the distal part gradually tapers.

In females, the 8th segment gradually tapers. The Sterigma has a semicircular ante-vaginal plate. The posterior sclerotization of the 7th sternite is semicircular and tapers laterally. The ductus bursae is slightly longer than the corpus bursae . The corpus bursae is slightly wrinkled and has two large signs.

distribution

Vulcaniella pomposella is common in Central Europe and in the north to Lithuania . The evidence from the Mediterranean and Eastern Europe has to be checked, as it is at least partially Vulcaniella cognatella and Vulcaniella grandiferella .

biology

The caterpillars develop on straw flowers ( Helichrysum arenarium ) and hawkweed ( Hieracium pilosella ). The species has also been observed in true sage , but this evidence probably relates to Vulcaniella cognatella . The specimens that were bred on the Hungarian sage ( Salvia aethiopis ) are Vulcaniella grandiferella . Vulcaniella pomposella probably forms two generations a year. The caterpillars mine in the leaves and hide in webs on the underside of the leaves. The feeding activity causes pale yellow spots to appear on the leaves. The caterpillars pupate in the mines. The moths fly from early May to early July.
