The serrated blueberry spanner ( Cepphis advenaria ) is a butterfly from the spanner family (Geometridae).

features

butterfly

The moths reach a wingspan of 24 to 30 millimeters. There is no difference in color between the sexes. The wing base color varies on the upper side from light brown to reddish brown and is provided with very fine dark brown dots. On the upper side of the forewing, the midfield is darkened and bounded by an inner and an outer dark brown transverse line, continues on the hind wings and protrudes towards the edge with a more or less pronounced spike. The drawing of the upper sides of the wings shines through in a similar form to the lower sides. A black discal spot is punctiform. The antennae of the males have long ciliates on both sides, those of the females have very short teeth.

Caterpillar

Fully grown caterpillars show a lateral zigzag band, which is composed of triangular, dark, white-bordered spots and turns into a brown marbled back color. It is characterized by a bright subdorsal blemish on the fifth segment.

Similar species

The two- striped moon spot spanner ( Selenia lunularia ) differs in its non-serrated outer transverse line, a dark brown field at the apex on the upper side of the forewing and the crescent-shaped glass spots on all wings. With a wingspan of 34 to 44 millimeters, the moths are also significantly larger than those of the jagged blueberry strainer.

distribution and habitat

The distribution area of ​​the jagged blueberry spider stretches across Europe, including the British Isles . The species is also found in the Altai , the Sayan Mountains , the Amur region , the Primorye region , Sakhalin and the Kuril Islands, as well as in eastern China , Korea and Japan . The main habitat are blueberry forests, heaths and moors. In the Alps , the species rises to an altitude of 1500 meters.

Way of life

The moths are mostly diurnal and fly in one generation from mid-May to mid-July. When at rest they keep the wings upright and half folded. At night they sometimes also appear in artificial light sources . The caterpillars feed primarily on the leaves of blueberries ( Vaccinium myrtillus ). Occasionally, which is baneberry ( Actea spicata ) or Wachtelweizen ( Melampyrum ) taken as food. The species overwinters in the pupal stage .
