In the males, the right brachium is slightly curved and distally widened. The apex is rounded. The left brachium is also slightly curved and rounded. The blades are parallel-walled. The right valvella is shorter than the distal part of the aedeagus . It is slightly curved, strong and very broad at the base. It gradually tapers towards the apex. The left valvella is long and gradually tapers. The distal part of the aedeagus tapers abruptly, the apex is curved.

Vulcaniella rosmarinella is drawn like Vulcaniella grabowiella , but differs in its glossy dark brown head, which is colored like the thorax. The tegulae are not edged white.

distribution

Vulcaniella rosmarinella is native to southern Europe ( Spain , France , Corsica ). In the east the distribution area extends to Greece and Crete . The species is also found in North Africa .

biology

The caterpillars develop on rosemary ( Rosmarinus officinalis ). The species is thought to have two generations a year. In spring and summer, the caterpillars mine in the leaves, which are often also woven together. The mines begin as an irregular feeding tunnel. The feeding tunnels are not very transparent and lined with silk on the inside. They occupy the upper half of the leaf, which causes the leaf to turn brown and contract. The caterpillars change mine a few times, a small hole is gnawed on the underside of the leaf in the middle. The caterpillar droppings are partially ejected through the entrance hole. The caterpillars pupate without a cocoon inside the mine. The moths fly from late May to July.
