Eteobalea dohrnii
Eteobalea dohrnii is a butterfly (moth ) from the family of the splendor butterfly ( Cosmopterigidae ). The species was named after Carl August Dohrn, President of the Stettin Entomological Society.
Features
The moths reach a wingspan of 10-16 millimeters. The head is yellowish white. The antennae are dark gray, in the last third, there are five white rings. The thorax shining ocher. The forewing shining ocher and are - especially in the apical half - brown speckled. A white spot is located near the forewing base at vane inner edge. To include drawing three white Costalflecke. The first is located at 1 /6 of the forewing length. It is long and runs obliquely outward to the anal cleft. The second spot is located at 2/ 5 and the third spot at 3/ 4 of the forewing length. The latter is more or less triangular. At the apex there is a white spot, which extends to the Frans shed into it. A total of five raised, gray-brown, golden shimmering spots are created. The first is small and externally connected to the first Costalfleck. The second is located just below the anal cleft between the first and second Costalfleck. The third spot is externally connected to the second Costalfleck. The fourth spot is in front of the wing inside edge just outside the third spot. The fifth spot is greatest. It is located at the inner angle, and often touches the third Costalfleck. Between the spot at the inner angle and the Apikalfleck some white lines are created. The hind wings are at the base of shiny white and yellowish gray toward the apex more. The abdomen is yellow ocher to dark gray. The ground color of the fore wings is variable, ranging a pale ocher- yellow to brown.
In the males, the Tegumen is long. It tapers distally light and has the rear edge of a "V "-shaped bulge. The right brachium is curved and approximately twice as long as the left. It is apically widened and heavily sclerotized. The left brachium is slightly curved and has a rectangular top. The Valven are trimmed boot -shaped. The right Valvella is narrow, it tapers gradually and has a rounded apex. The aedeagus is bent and has a very sharp tip. The bulbous portion is oval, the tubular member is parallel walls.
In females, the eighth segment is longer than wide. The ostium is semicircular. The sterigma is bell-shaped, the ventral margin is strongly sclerotized. The ductus bursae is about one and a half times as long as the corpus bursae. The corpus bursae is oval and has a long bulbous rear, gradually tapering extension. It formed two large, crescent-shaped signals of different sizes.
Similar Species
Eteobalea dohrnii similar Eteobalea siciliae, but differs by the absence of lines on the fringe scales at the apex of the forewing.
Dissemination
Eteobalea dohrnii is native to the Mediterranean. The distribution area extends from Portugal in the west to Syria in the east.
Biology
The caterpillars develop in the roots of white lichen plantain ( Plantago albicans). The moths fly from May to early October. The species probably forms two generations per year.
