Anania funebris
Anania funebris
Anania funebris is a (small) butterfly of the family Crambidae.
Features
The moths have a wingspan of 21 mm (or a front wing length 9-10 mm). Front and hind wings are black. Each wing has in each of two large, sharply drawn white spots. On the forewing the distal spot located approximately in the middle between the front and inner edge. It is generally elliptical, and is transverse to the longitudinal axis of the wing. The proximal spot is round to slightly längselliptisch, rarely angular direction, and is located near the inner edge. On the forewing often occurs even on a third, small stain. This has a very variable size and can occasionally be absent. It lies on the level of the proximal spot, but closer to the edge Kostal. He is often very washy, rarely sharply drawn, sometimes längselliptisch. The tegulae are ocher yellow.
The caterpillar is yellowish white and has green longitudinal lines. The head is brownish white.
The doll is colored from 8.5 to 10.0 mm long and reddish brown. The surface is finely papillose, sometimes even wrinkled. The Darkened cremaster is relatively long and blunt at the end. The bristles are hook-shaped and focused on Kremasterende.
Geographical distribution
The species is widespread in Central and Northern Europe, very local in southern Europe. The distribution area extends further over southern Siberia and Transbaikalia to the Russian Far East and in the Nearctic. It is also detected in Armenia.
The species prefers dry, but also fresh sites in the open countryside and forest edges. It is distributed very local and usually rare. In the Alps, it rises to at least 2300 meters.
Way of life
The species form two generations per year, flying their Falter May to August. The moths are diurnal and fly mostly to the food plants of the caterpillars around. The oligophagen caterpillars feed on goldenrod (Solidago ), dyer's broom ( Genista tinctoria ) and Schwarzwerdendem Geißklee ( Cytisus nigricans ). The caterpillar lives between co- spun flowers or produces a cocoon tube on the lower leaves of the food plant on. The caterpillar overwinters and pupates in the spring.
Systematics and Taxonomy
The taxon was described in 1768 by Hans Strøm (also spelled Hans Ström ) as Phalaena Geometra funebris first time scientifically. The name was often viewed as a synonym of Phalaena octomaculata Linnaeus, since the publication date of the latter type had been incorrectly determined (1767 instead of the correct 1771). This species is the type species of the genus Anania Hübner, 1823. Phalaena octomaculata Linnaeus, 1771 is now considered as a synonym of Anania funebris.
