Vulcaniella grandiferella
Vulcaniella grandiferella is a butterfly (moth ) from the family of the splendor butterfly ( Cosmopterigidae ).
Features
The moths reach a wingspan 8-13 mm. Males and females are similar Vulcaniella pomposella, but differ by the larger wingspan, the more elongated, pointed forewings in males, the broad silvery edge of the tegulae and the fahlere abdomen. A reliable differentiation is possible only through an examination of the genitals.
The genital armature of the males differs from Vulcaniella pomposella through the apical broader right brachium, the wider Valven with a narrow base and slightly curved distal part and the broader, significantly shorter right Valvella.
The genital armature of females differs from Vulcaniella pomposella by the longer, leaner apophyses. The Antevaginalplatte is broad and semicircular. The sclerotization of sternite 7 is large and triangular. The corpus bursae is heavily wrinkled.
Dissemination
Vulcaniella grandiferella is in the eastern Mediterranean and the Balkans to the Caucasus spread (Serbia, Montenegro, Greece, Macedonia, south of the European part of Russia, Ukraine).
Biology
The caterpillars develop in Hungary sage ( Salvia aethiopis ) and clary sage (Salvia sclarea ). You nate in the leaves, especially in those who are on the ground. The mines are irregular in shape and are usually located between the leaf main veins at the base of the leaf. Change The caterpillars mine several times and spend most of their time outside of the mines in web courses at the underside of leaves. The Raupenkot is ejected and collected at the mine entrance. The caterpillars pupate in a loose cocoon between the hairs on the leaf surface or on the stem. The species is normally bivoltin, under favorable conditions, up to four generations are formed in the year. On the Crimean peninsula, the first generation flies from mid-May to early July and the second generation of July to August.
