Cosmopterix salahinella is a butterfly ( moth ) from the family of cosmopterigidae (Cosmopterigidae).
features
The moths reach a wingspan of 10 to 12 millimeters. The species resembles Cosmopterix lienigiella , but differs from it by the narrower forewings and the broad center line in the basal region of the forewings. This extends from the base of the wing to the yellow band. In some specimens from Tunisia, the white center line is less pronounced.
The genital armature of the males also resembles the similar type mentioned above, but differs in the short, rounded hump on the right brachium and the less developed hump on the right valvella .
The genital armature of the females differs from the similar species by the less strongly curved, rear end of the 7th sternite and the smooth and pointed rear part of the ostium .
distribution
Cosmopterix salahinella is widespread in Tunisia , Egypt , Libya , Israel and to the east as far as Saudi Arabia and Iran .
biology
The caterpillars develop on reeds ( Phragmites australis ). They mine in the leaves and can be found from summer to February. The mines cannot be distinguished from Cosmopterix scribaiella . The caterpillar droppings collect in the lower, narrow part of the mine and are sometimes also ejected. The caterpillars pupate inside the mine, the moths hatch from late January to late May. In Egypt the species forms two generations a year and mines there in the leaves of the pile tube ( Arundo donax ). Since the host plant is used commercially, Cosmopterix salahinella is considered a pest. The infestation rates fluctuate very strongly and are between 4.8 and 45.7 percent. The caterpillars and pupae are infested with parasitoids to an average of 20 percent . These parasitoids are especially jewel wasps of the genus Pediobius and Brachymeria .
