The sulfur-yellow hair- tufted spanner ( Gandaritis pyraliata ) is a butterfly ( moth ) from the spanner family (Geometridae). In the literature, the species can also be found as Eulithis pyraliata , Lygris pyraliata or Larentia dotata .

features

butterfly

The moths reach a wingspan of 27 to 34 millimeters. There is no difference in color between the sexes. The upper side of the forewings has a sulfur-yellow, straw-yellow or ocher-brown basic color, from which two mostly weakly developed, strongly jagged brown transverse lines stand out, which frame the slightly darkened middle field. Sometimes brown arrow spots stand out towards the hem. The fringes are always unchecked. At Apex , a short dark dividing line runs. The upper side of the hind wing is pale yellow without drawing.

Caterpillar

Adult caterpillars are greenish in color, have a thin, dark back line and broad white side back lines.

Similar species

The honey-yellow hair-tuft tensioner ( Eulithis mellinata ) differs in most specimens by the distinctively developed and very dark transverse lines on the upper side of the forewing . However, the main distinguishing feature is the brown / white piebald fringes.

Distribution and occurrence

The distribution area of ​​the sulfur-yellow hair-tuft spanner stretches from Spain , France and the British Isles through Central Europe eastwards to Mongolia and the Amur . The northern distribution extends almost to the Arctic Circle . The species is also found in the Altai and through Siberia to northeast China . The main habitat are mixed forests, wetlands and bushy meadows as well as gardens and parks. It also occurs in urban areas. The altitude distribution reaches up to 1900 meters in the Alps and up to 2300 meters in the Caucasus .

Way of life

The crepuscular and nocturnal moths are univoltine and mainly fly in the months of July and August. At night they visit artificial light sources , and sometimes bait . In their typical resting position, the moths push their hind wings completely under the forewings and turn the inner edge upwards. In addition, the end of the abdomen is bent slightly upwards. The eggs are simply dropped by the female over a food crop. The egg hibernates. The caterpillars feed on the leaves of different types of bedstraw ( Galium ). The pupation takes place on the ground between plant parts.
