The single- lined dry lawn spanner ( Aspitates gilvaria ) is a butterfly from the spanner family (Geometridae). The species name is derived from the Latin word gilvus with the meaning "yellow" and refers to the basic color of the butterfly.

features

butterfly

The moths reach a wingspan of 26 to 32 millimeters. The color of the forewing surface varies from straw yellow to cream and shows a weak brownish pollination. An outer transverse line beginning in the apex and running diagonally to the inner edge stands out brownish. A very small discal spot also has a brownish color. The upper side of the hind wing is poorly colored white-yellow and provided with a weak center and an indistinct gray transverse line, translucent from the underside. The antennae of the males are combed, those of the females have short teeth.

egg

The egg initially has a light green color, which changes from reddish yellow to gray shortly before the caterpillars hatch . The pole and the bottom of the egg are orange. The surface is covered with about 50 longitudinal ribs. The micropyl rosette has ten to eleven leaves and is surrounded by a large-meshed network.

Caterpillar

Fully grown caterpillars are colored yellow-brown to dark brown with little drawing and are slightly lightened on the ventral side. They have two anal tips known as paraprocts .

Similar species

The moths of Aspitates ochrearia are distinguished by an additional thin gray inner transverse line on the upper side of the forewing .

distribution and habitat

The distribution area of ​​the single-lane dry grass moth extends from the Iberian Peninsula across Western and Central Europe to Russia and through the Mediterranean region to the Black Sea region and the Caucasus . The species is represented in Finland and the Baltic States by the subspecies Aspitates gilvaria fenica (Fuchs 1899), in Ireland by Aspitates gilvaria burrenensis Cockayne, 1951 and in Central Asia and Siberia by Aspitates gilvaria orientaria (Alphéraky, 1892). The main habitat are warm slopes, heathland areas, field margins and abandoned quarries. In the mountains, the species rises to heights of 1000 meters.

Way of life

The moths are diurnal and nocturnal. They fly in one generation from late June to early September. At night they appear on artificial light sources . The caterpillars feed polyphagously on a variety of different plant species. They overwinter in their youth stage and are fully grown in June of the following year.
