Features

The moths reach a forewing length 9.5 to 11.4 mm in males and from 9.4 to 10.5 mm in females. The head is especially at forehead ( frons ) and vertices (vertex ) hairy and shimmers brownish green, brown or black brown. The forehead is about twice as wide as the compound eyes. The sensors are strongly clavate, shimmering olive green or dark green. They consist of 35 to 37 segments; the last eight segments are broad to platelets. The thorax dorsal shimmers green or brownish green, sometimes it is only black and dull. The rear end is covered with long hair. The tegulae are hairy and shimmer gold green, legs shimmering green laterally, medially they are lackluster. The abdomen shining green or bluish green. The front upper wing surface shimmers bright green and has a variable gloss. The hind wings are dark gray or light gray and slightly translucent. The wing undersides are light gray. Sometimes located in Analwinkel of the hind wings, a narrow strip of blue shimmering scales. The females resemble the males in size and coloring. The sensors are weak doubly serrate, almost filiform and thickened strongly club-shaped at the end.

In the male the uncus is very large and heavily sclerotized. The Valven are wide and have no extensions. The aedeagus is slender and slightly curved upwards. Proximal it is provided slightly thicker and with a short, straight and slender cornutus.

In females, the ostium is lip-shaped. The antrum is long, strongly sclerotized and has a smooth surface. The ductus bursae is short and translucent, folded longitudinally and distally rotated. The corpus bursae is ovoid.

The egg is 0.8 millimeters long, 0.5 millimeters wide and 0.4 millimeters high. It is pale yellow in color and provided with fine longitudinal ribs.

The caterpillar goes through 6-8 stages. In the first stage it is about 1.1 mm long and 0.3 mm wide. The head is brown, the body light yellow. On the back of the first Thorakalsegments is a T-shaped sclerotized plate. The L1 stage lasts 6 to 14 days.

The caterpillars of the second stage are 2.0 mm long and have a bright yellow body. On the back there is a light brown line. Head and Prothorakalplatte are brown. The Torah calf A light brown, the belly legs pale yellow. The L2 stage lasts 5 to 16 days. In the third stage, the caterpillars are 2.5 mm long and bright yellow. The back line and the side line of the back are light brown. The L3 stage lasts 6 to 21 days.

In the fourth stage, the caterpillars are 3.5 mm long and gray yellow and have light brown back, side back and side lines. The abdominal legs and the ventral portion of the abdomen are yellow. On the back line there are prickly Makrotuberkel. The Peritrema - an annular sclerite surrounding the breathing holes - is dark brown. The L4- stage lasts 12 days, in case of diapause 258-277 days.

The caterpillars of the fifth stage are 3.5 to 4.0 millimeters long and dyed much darker compared to the previous stages. The back line and the side ridge lines are reddish brown. The back line is divided by a white line. The side line and the Basallinie are light brown. The dorsal and subdorsal located warts are orange and white lined, which are located laterally and ventrally yellow. The abdominal legs and the ventral portion of the abdomen are yellow. The light brown Peritrema is on the sidelines only poorly visible. Makrotuberkel are now both on the back line as well as on the side back line available. Most are einstachlig, some mehrstachlig. The L5- stage lasts 12 to 28 days.

In the sixth stage, the caterpillars are 3.8 to 4.5 millimeters long. You may already be an adult at this stage and then have a length of 8.0 to 12.5 millimeters. They are similar to the L5 stage, but are darker. The side lines are brown, the Basallinie is dark brown. The subdorsal warts are located laterally lined light brown and white. The laterally situated warts are light brown, the dorsal yellowish gray. The ventral part of the abdomen is yellowish gray, the abdominal legs are yellow. The number of Makrotuberkel on the back, side back and side line has increased, even on the Basallinie are some available. The L6- stage lasts 12-41 days.

The caterpillars of the seventh stage are 5.0 to 5.5 millimeters long, colored much larger and darker. The black-brown dorsal line is divided by a gray center line. The side ridge lines are light brown and dorsal and ventral lined gray. The lateral and ventral warts are brown, the ventral portion of the abdomen is gray-brown, the abdominal legs are orange. Head, Prothorakalplatte and Torah calf A are dark brown. The Peritrema is gray. The prickly Makrotuberkel are densely arranged in particular on the back and side of the back. The L7- stage lasts, including the diapause 159-182 days.

In the eighth stage, the caterpillars are 8.0 millimeters long and well colored as in the previous stage. The Makrotuberkel are mehrstachlig, the sting have a crown-shaped top. The Mikrotuberkel are einstachlig and taper to a point. While the caterpillars make the cocoon, they turn around. The dorsal warts are brighter and form a broad pale yellow band. The color of the lines and the other warts hardly changes. For the making of the cocoon, the caterpillar will need six to eight days, the L8- stage takes 22 to 23 days.

The cocoon is spindle- shaped, and from 10.0 to 12.5 millimeters long. It consists of white, not very dense silk. The doll is from 7.2 to 8.5 millimeters long. Head, thorax, wings and abdomen are smooth and shining light brown. The abdomen is dark brown dorsal line and an equally colored by back line can be seen.

In the Balkans and Turkey Adscita capitalis is the only species of the genus with strongly club-shaped antennae.

Dissemination

Adscita capitalis is in Macedonia, Greece ( including the island of Samos ) and Turkey disseminated. The species colonized wet meadows. In Turkey, the moths are to be found up to 3000 meters altitude.

Biology

The females lay eggs singly or in small groups of two to three Units in the thick hairy top leaves of the food plant from. Under farming conditions, the duration of the egg stage was variable, it was 5-15 days. As a forage plant the Grey Rockrose ( Helianthemum canum ) was detected. Under farming conditions, other species such as Helianthemum sun Rösch georgicum and the Yellow Rockrose ( Helianthemum nummularium ) were accepted by the crawler. In captivity, the caterpillars of the first three stages designed short gallery-like mines in the leaves of H. at georgicum. In the case of H. nummularium the caterpillars ate only the parenchyma of the leaves, making small furrows created. On the Crimean peninsula and the large flower Rockrose ( Helianthemum grandi floris ) was adopted as a forage crop. The caterpillars wintered in rearing in Austria L4 stage and pupated in the L6 stage. When rearing in the Crimea, however, they wintered in the L7- stage and pupated in the L8- stage. Observations from the field are not yet available. While the caterpillars make the cocoon, they turn around. The pupal period lasts 15 to 19 days. The moths emerge in the morning, the flight time is from June to July.
