The beaver moth ( Eupithecia pimpinellata ) is a butterfly ( moth ) from the family of the spanners (Geometridae). The specific epithet refers to the beaver cells ( Pimpinella ), the food plants of the caterpillars.

features

butterfly

The wingspan of the moth is 17 to 25 millimeters. The basic color of all wings varies from ash gray to reddish gray. The discoid spot on the upper side of the forewing is black and elongated. The transverse lines are extended to dark spots at the front edge . The whitish wavy line stands out clearly. The hind wings are slightly lightened in the basal region . The abdomen is gray to gray-brown in color and shows a few short tufts of black-brown hair. A dark brown saddle can be seen on the second segment.

Caterpillar

Adult caterpillars are smooth and slender. They occur in two forms and are either greenish in color and show yellow segment incisions or are almost solid red.

Doll

The brownish pupa is provided with green or yellow wing sheaths. There are eight hook bristles on the dark brown cremaster , the middle pair of which is strong.

Similar species

  • The thyme moth ( Eupithecia distinctaria ) lacks the brown saddle on the second abdominal segment.
  • The tooth rust pomegranate ( Eupithecia pauxillaria ) is pale gray in color than E. pimpinellata .

A genital morphological examination can also be carried out in the case of specimens that have been flown away a lot .

Distribution and occurrence

The distribution of the species extends from the Iberian Peninsula through Western and Central Europe including the British Isles and further east to the mountains of Central Asia. In Russia and the Altai it is represented by the subspecies ( E. pimpinellata altaicata ), in China by ( E. pimpinellata vellicata ). In the north the area extends into central Fennoscandinavia , in the south through the Mediterranean region to the Balkan peninsula . An isolated population occurs in the Atlas Mountains in Morocco .

The Bibernelle-flowering moth populates primarily bushes, forest edges, clearings, hedges, mountain slopes, embankments, railway embankments and parks as well as semi-arid lawns. In the Alps it rises to altitudes of 1,800 meters.

Way of life

The main flight time of the crepuscular and nocturnal moths falls in the months of July and August. To eat, visit the flowers of dost ( Origanum ), thyme ( Thymus ), scabiosa ( Scabiosa ) or bedstraw ( Galium ). They are easily attracted by artificial light sources . Eggs are laid on the flower buds or on the stems under the flowers of the food plant. The caterpillars live from mid-August to mid-October and feed first on the flowers until pupation, later on the fruits of the small beagle ( Pimpinella saxifraga ), sometimes also on the large beaver ( Pimpinella major ) or other umbellifers (Apiaceae). The species overwinters in the pupal stage.

Danger

The beaver moth occurs in Germany in the individual federal states in different population densities and is classified as "not endangered" on the red list of endangered species .
