Phibalapteryx virgata ( Syn . : Mesotype virgata ) is a butterfly fromthe Spanner family (Geometridae). The common name "Streifenspanner", which is sometimes used, is not unambiguous, as the plane tensioner ( Plagodis dolabraria ) is sometimes also referred to by this name. The common names bedstraw leaf tensioner, light gray bedstraw tensioner and limestone-dry lawn strip tensioner are only used occasionally. The species name is derived from the Latin word virga with the meaning "stripe" and refers to the drawing on the upper forewing of the butterfly. In English usage, the type is called Oblique Striped called (the diagonally striped).

features

butterfly

The moths reach a wingspan of 17 to 23 millimeters. There is no sexual dimorphism between the sexes in terms of color , but the females are somewhat smaller and narrower than the males. The wing color varies on the upper side from ocher to light gray and brown-gray. The discal region is bordered by dark, light, stripe-like, sometimes very wide and distinctive transverse lines and contains a punctiform discoidal spot . In Apex , a short dark slash takes off. Sometimes a thin dark brown line, interrupted several times, runs in front of the hem. The upper side of the hind wing is colored light gray-brown and streaked with some more or less clear transverse lines.

Caterpillar

Adult caterpillars are very slender and gray-brown to red-brown in color. The stigmas are black, the belly and flanks are yellow.

Similar species

  • The gorse heather wavy stripe tensioner ( Scotopteryx coarctaria ) differs by a whitish wavy line on the upper side of the forewing .
  • The marsh weed leaf tensioner ( Orthonama vittata ) differs in its overall lighter overall appearance as well as a line made up of many very small black dots directly on the edge of the fore and hind wing tops . The outer transverse line ends without interruption in the apex.

distribution and habitat

Real bedstraw ( Galium verum ), the main food of the caterpillars

The range of Phibalapteryx virgata extends from the Amur area through the temperate zone to Europe, where the occurrence is however patchy. The species is also found in the British Isles . The main habitat are dry areas, such as juniper heaths, dry grasslands, warm slopes and dry moorland meadows. In coastal regions it is often found in the dunes .

Way of life

The moths are mostly nocturnal and fly in two generations from late April to early June and from late June to mid-August. At night they appear on artificial light sources . During the day they can easily be shooed out of the vegetation. The caterpillars feed primarily on the leaves of real bedstraw ( Galium verum ), sometimes also on other lower plants. The second generation overwinters in the pupal stage .

Danger

Phibalapteryx virgata is in the German states in different numbers, but usually sporadically represented and is on the red list of endangered species out in most areas in category 2 ( "high risk") in Baden-Wuerttemberg , however, "near threatened".
