Eteobalea dohrnii is a butterfly ( moth ) from the family of cosmopterigidae (Cosmopterigidae). The species was named after Carl August Dohrn , the president of the Szczecin Entomological Association.
features
The moths reach a wingspan of 10 to 16 millimeters. The head is yellowish white. The antennae are dark gray, in the last third there are five white rings. The thorax has a shiny ocher color. The front wings have a glossy ocher color and - especially in the apical half - are speckled brown. A white spot is near the base of the forewing on the inner edge of the wing. Three white costal spots belong to the drawing. The first is at 1/6 the fore wing length. It is long and sloping outwards to the anal fold. The second spot is at 2/5 and the third spot is at 3/4 of the forewing length. The latter is more or less triangular. At the apex there is a white spot that extends into the fringed scales. A total of five raised, gray-brown, golden shimmering spots are created. The first is small and externally connected to the first costal spot. The second is just below the anal fold between the first and second costal spots. The third spot is externally connected to the second costal spot. The fourth spot is in front of the wing inner edge a little outside the third spot. The fifth spot is the largest. It is located on the interior corner and often touches the third costal spot. A few white lines are drawn between the spot at the inner corner and the apical spot. The hind wings are glossy white at the base and more yellowish gray towards the apex. The abdomen is ocher yellow to dark gray. The basic color of the forewings is variable and ranges from a pale ocher yellow to brown.
In the male, the tegumen is long. It tapers slightly distally and has a “V” -shaped bulge on the rear edge. The right brachium is curved and about twice as long as the left. It is dilated apically and severely sclerotized . The left brachium is slightly curved and has a rectangular tip. The blades are clipped, boot-shaped. The right valvella is narrow, it gradually tapers and has a rounded apex. The aedeagus is curved and has a very sharp point. The bulbous part is oval, the tubular part is parallel-walled.
In the females, the eighth segment is longer than it is wide. The ostium is semicircular. The sterigma is cup-shaped, the ventral margin is heavily 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, gradually tapering process behind. There are two large, sickle-shaped signs of different sizes.
Similar species
Eteobalea dohrnii is similar to Eteobalea siciliae , but differs in the absence of the lines on the fringed scales at the apex of the forewings.
distribution
Eteobalea dohrnii is native to the Mediterranean area . The distribution area extends from Portugal in the west to Syria in the east.
biology
The caterpillars develop in the roots of the white plantain ( Plantago albicans ). The moths fly from May to early October. The species is thought to have two generations a year.
