Features
Butterfly
The moths have transparent wings, but these are scaly to the wing veins, the Diskalfleck and the wing edges. You can reach a wingspan of 12-30 millimeters. The front wings are dusted reddish to yellowish in the seam area. The fringes are black. In the middle is a broad, black-brown Diskalfleck that extends from the front to the back edge to the outside is reddish limited and reveals a small pointed bulge inward. The trailing edge has sometimes a red-orange color. The hind wings have a narrow dark Saumbinde and a small black brown Diskalfleck. Thorax and abdomen are black. Up to the first segment show all other segments of the abdomen clear yellow rings. The head is hairy yellow white. The front third of the sensor is - especially in the females - yellowish and provided with a black tip. The after tuft is black and yellowish hairs only in the middle and on the sides.
Similar Species
There is a great similarity to other Bembecia spp:
- The male of the rest-harrow - wing moth ( Bembecia albanensis ) is missing the inward tip at Diskalfleck the forewing, also the Diskalfleck of the hind wings is yellowish. In females the anus Busch is always monochrome yellow.
- Bembecia megillaeformis has only three yellow rings on the abdomen in males and four in females.
- Bembecia uroceriformis differs by the always monochrome yellow after bush.
- Bembecia illustris shows an overall brighter appearance.
Since the outer differentiators in the above species to Bembecia ichneumoniformis are low, a reliable determination should be done by specialists, and also a genitalmorphologische analysis is recommended for the unique assignment.
Geographical distribution and occurrence
The trefoil - clearwings is used in almost all of Europe. He also comes from Asia Minor to Transcaucasia and in northern Iran, Palestine and Syria. The species was still detected at altitudes of 1800 meters. Their main habitat is dry grasslands, heathland, Ödländereien, scree slopes, warm slopes and forest edges.
Way of life
The diurnal moths fly during the months of June to August, at higher altitudes to September. Since Their proboscis is stunted, they can not feed. Male moths also fly to pheromone traps. The maggot-like caterpillars live one-or two -year in the roots of various plants, these include: Common birdsfoot trefoil ( Lotus corniculatus ), Common horseshoe vetch ( Hippocrepis comosa ), silk -Back clover and Spiny rest-harrow ( Ononis spinosa ) ( Dorycnium pentaphyllum subsp anglicum. ). The caterpillars overwinter and pupate in the spring in a long tube spun at the root of the food plant.
Endangering
In Germany, the trefoil - clearwings occurs in all states and is classified as endangered.
