The yellow ocher leaf tensioner ( Camptogramma bilineata ), often also called wave tensioner , is a butterfly ( moth ) from the tensioner family (Geometridae). It is also known as the dandelion wrench or nettle wrench.

features

The wingspan is about 20 to 30 millimeters. The basic color of the fore and hind wings is yellow to ocher brown. Animals that are lightened gray-brown are also occasionally observed. Fore and hind wings are covered with brown or white serrated transverse lines. Usually there are three or four clear white cross lines that can be bordered by a black line. The continuous hemline is black and wavy. Due to the white and dark transverse lines, it cannot be confused with any other species.

The yellowish eggs are round, only slightly flattened at the pole. The surface shows a large meshwork. Warts sit on the crossing points.

The caterpillars are greenish to slightly brownish with clear segment incisions. The back line is darker than the body color. The sideline, on the other hand, is often lighter. The head is usually light brown and relatively small.

The doll is red-brown with a short cremaster consisting of two small bristles. The thoracic area and the wings have a brownish-greenish hue.

Way of life

The yellow ocher leaf tensioner flies in two generations from mid-May to mid-July and from mid-July to late September. The second generation can be partial in climatically unfavorable areas. The moths are diurnal, but also fly at dusk or at night and come to light. They suck on flowers. The food plants of the moths include:

The caterpillars feed on a wide variety of plants, such as B .:

The caterpillars overwinter. They pupate in the ground in spring.

Habitat

The species shows no preferences for specific biotopes. It flies in the forest and open land, as well as in damp and dry places. However, a higher density of butterflies was found on weed-rich forest fringes. In the Alps it occurs up to an altitude of 1,600 meters. It is found frequently, but also in very different numbers from year to year.

distribution

The yellow ocher leaf tensioner is widespread from North Africa and the Iberian Peninsula across western and central Europe including the British Isles to the Altai in the east. In the north the distribution area extends to northern Fennoscandia , in the south to Malta . The south-west extension of the distribution area includes the western Mediterranean , the Balkan countries as well as Asia Minor , Northern Iran and Turkmenistan .
