The Ampferspanner ( Timandra comae ), also called Liebling or Rotrandspanner , is a butterfly ( moth ) from the Spanner family (Geometridae).

features

Copy with only a weak median point. The inner transverse line is missing.

The Ampferspanner is a medium-sized moth with a wingspan of 23 to 28 millimeters. It is colored ocher to pale and has a reddish to purple-colored line on the fore and hind wings, which together form a line when at rest. This line is made up of the center line, which runs in a straight line towards the apex and merges with the outer transverse line in the border area, but in some specimens ends shortly before the merger. The outer transverse line is an irregular gray line in the rear and middle part of the border area and becomes a red line running straight to the apex in the front part. The outer edges of the wings are colored light pink to pink. A dark median point (center point) can be seen on the forewings, but it can also be very weak. The inner transverse line is most strongly developed at the rear edge of the wing and becomes more indistinct towards the costal edge (front edge).

The species complex Timandra comae / Timandra griseata is difficult to separate. After Ebert is in occurring in Germany populations but to Timandra comae while the sister species Timandra griseata in north-eastern Europe occurs.

Flight and caterpillar times

The Ampferspanner forms two to three overlapping generations per year. According to Ebert, two generations are given for central Germany from mid-May to late June and from mid-July to early October. In hot years, the flight times shift so that an incomplete third generation is trained.

habitat

The Ampferspanner often occurs in humid areas, but also in dry places. In the cultivated land you can find the species on abandoned fields, abandoned vineyards, embankments, dams, sand and gravel pits. Furthermore, it can be found almost in the entire settlement area.

Way of life

The oviposition was observed on different parts of the plant. Findings of caterpillars are documented on Rumex acetosa and Rumex obtusifolius , while the adult caterpillars sat on the upper leaves or on the flowers and seeds of the plant. The caterpillars feed on different dock species ( Rumex spec. ) And knotweed species ( Polygonum spec. ):

In the Oberrheinebene moth when flowers were you at Natternkopf ( Echium vulgare ), heather ( Calluna vulgaris ) and Solidago canadensis ( Solidago canadensis ) was observed. During the day the moths rest with widely spread wings on leaves or hidden in bushes. The characteristic interweaving transverse band of the fore and hind wings dissolves the physical outline of the butterfly from its environment and effects an effective camouflage ( somatolysis ). The moths become active towards evening or when the sky is overcast and also come to light at night. The second generation caterpillars overwinter in central Germany.

distribution

The Ampferspanner is widespread, but it is seldom noticed because it lives rather hidden. In the south, its distribution reaches North Africa , the Iberian Peninsula , the islands of the western Mediterranean via Italy and the Balkans to Asia Minor and Turkmenistan . Furthermore, the dock spanner is widespread in western and central Europe including the British Isles , in Fennoscandinavia , in the Baltic States and in Russia . The sister species Timandra griseata replaces the dock spanner from southern Sweden and in the Baltic States. In the east (up to Japan ) other species of this group are added: Timandra recompta ( Prout , 1930), Timandra paralias ( Prout , 1954).
