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

features

The moths reach a wingspan of 8 to 13 millimeters. Males and females are similar to Vulcaniella pomposella , but differ in their larger wingspan, the more elongated, pointed fore wings in the males, the broad, silvery edge of the tegulae and the paler abdomen . A reliable differentiation is only possible by examining the genitals.

The genital armature of the males differs from Vulcaniella pomposella by the apically wider right brachium , the wider valves with a narrow base and slightly curved distal part and the broader, significantly shorter right valvella .

The genital armature of the females differs from Vulcaniella pomposella by the longer, slimmer apophyses. The anterior vaginal plate is wide and semicircular. The sclerotization of the 7th sternite is large and triangular. The corpus bursae is very wrinkled.

distribution

Vulcaniella grandiferella is common in the eastern Mediterranean and from the Balkans to the Caucasus ( Serbia , Montenegro , Greece , Macedonia , south of the European part of Russia , Ukraine ).

biology

The caterpillars develop on Hungarian sage ( Salvia aethiopis ) and clary sage ( Salvia sclarea ). They mine in the leaves, especially those on the ground. The mines are irregular in shape and are usually located between the main leaf veins at the base of the leaf. The caterpillars change mine several times and spend most of their time outside the mines in webs on the underside of the leaves. The caterpillar droppings are thrown out and collect 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 usually bivoltine , and under favorable conditions it can produce up to four generations per year. On the peninsula of Crimea , the first generation flies from mid-May to early July and the second generation of July to August.
