The pelurga comitata ( Pelurga comitata ) is a butterfly ( moth ) from the family of the tensioner (Geometridae).

features

The moths reach a wingspan of 25 to 30 millimeters. The front wings are yellow and have a brownish colored root field. The middle field is wide, is crossed by several transverse lines and is more or less dark on the inside. The basic color of the forewings differs only slightly, the color of the central band varies between pale and dark brown tones, inside it can also be lightened. The outside of the midfield is bordered by a dark transverse line that jumps in a jagged manner to the hem. The apex is divided by a dark line. The light border is drawn with an indistinct wavy line, which is shaded on the inside by brownish spots. The hind wings are yellowish gray and have indistinct transverse lines.

The caterpillars reach a length of about 23 millimeters and are relatively thick. The skin is rough and pale ocher in color, above the spiracles it is provided with a gray-black pattern. There is a pale zigzag line on each side while the back has a series of dark diamond drawings. The head is drawn whitish and dark brown.

Synonyms

  • Phalaena comitata Linnaeus, 1758
  • Larentia comitata

distribution

The species is widespread in temperate Europe.

Way of life

The females lay eggs in July, from which the caterpillars hatch in August. They are nocturnal and eat u. a. on flowers and fruits of the following food plants:

During the day, the larvae hide themselves curled up like the number "2" in the fruits of the forage plants. The individually living caterpillars are fully grown in September and then pupate in a protected place in loose earth in a light web. The pupae overwinter, the moths hatch in July of the following year. The pupae hibernate occasionally a second time.

Bergmann describes the butterfly as "the leading species of rubble perennial corridors with abundant stocks of forage plants on sunny slopes of fresh earth and gravel hills in open corridors of the warm, dry areas of the plains". The adults hide on the ground during the day, and at night they can be found on flowers, artificial light sources or bait.

Flight and caterpillar times

The report leaf tensioner forms a generation a year that flies from mid-June to mid-September. The caterpillars can be found from August to September.
