Vulcaniella pomposella
Vulcaniella pomposella is a butterfly (moth ) from the family of the splendor butterfly ( Cosmopterigidae ).
Features
The moths reach a wingspan 8-10 mm. The head shining dark brown and golden sparkles. The antennae are curled dark brown and in the first three quarters white. In the last quarter there are five white segments that are separated by three dark brown segments. The thorax and tegulae shining dark brown and golden glitter. Both are lined in each case at the rear end with silvery scales. The forewing shining dark brown and golden glitter. A slanting outward, raised, silvery binding is located at 1 /6 of the forewing length and ranges are about the anal fold out. For casement drawing include six sublime silvery spots. Two are located on the Costa loader. The first is before the half wing length and the second at 3/4 of the front wing length with a white line that extends from the Costa loader to the Frans shed. Three other spots are located at the inner edge of wing. The first is located forward of the wing center on the anal fold, the second wing on the inner edge between the two Costalflecken. The third is located at the inner angle. At the apex there is a white spot. The fringe scales are dark brown and gray at the apex around and at the wing base. The hind wings shining gray and are at the apex more brownish. The abdomen is dorsally dark gray. The forewings of females are distinctly constricted before the apex, the abdomen is ocher brown.
In the males the right brachium is bent inwardly and distally strongly rejuvenated. The apex is slightly dilated. The left brachium is thickened in the middle and has a rounded apex. The Valven are wider at the base, the distal half is straight. Valvella the right so long as the Valven. It is slightly wider at the base and has a rounded tip. The basal part is ventral bulbous. The left Valvella is short and tapers gradually. The aedeagus is straight, the distal part tapers gradually.
In females, the eighth segment is tapered gradually. The sterigma has a semicircular Antevaginalplatte. The posterior sclerotization of sternite 7 is semi-circular and tapers laterally. The ductus bursae slightly longer than the corpus bursae. The corpus bursae is provided slightly wrinkled and with two large signals.
Dissemination
Vulcaniella pomposella is widespread in Central Europe and in the north to Lithuania. The evidence from the Mediterranean and Eastern Europe need to be checked, as it is at least partially is here to Vulcaniella cognatella and Vulcaniella grandiferella.
Biology
The caterpillars develop on sandy immortelle ( Helichrysum arenarium ) and mouse-ear hawkweed ( Hieracium pilosella ). The species was also observed in skipjack sage, but this evidence presumably refers to Vulcaniella cognatella. In the specimens that have been bred to Hungary sage ( Salvia aethiopis ) is Vulcaniella grandiferella. Vulcaniella pomposella probably forms two generations per year. The caterpillars nate in the leaves and hide in web courses at the underside of leaves. By feeding activity arise pale yellow spots on the leaves. The caterpillars pupate in the mines. The moths fly from early May to early July.
