Features
The Ampferspanner is a medium sized moth with a wingspan of 23-28 millimeters. He is ocher- colored to pale ocher and wearing one each on the front and rear wings, which together form reddish to purple line in rest position a line. This line is made up of the center line, the direction of Apex runs in a straight line and merges in Saumfeld with the outer transverse line in some specimens but ends shortly before the merger. The outer transverse line is an irregular gray line in the back and middle part of the Saumfeldes and is in the front part to a straight line to the apex extends red line. The outer wing edges are light pink to pink colored. On the fore wings a darker median point (center ) is seen, which, however, may be very weak. The inner transverse line is most developed at the trailing edge of the wing and is used to Costalrand ( front edge ) out blurry.
The Artkomplex Timandra comae / Timandra griseata is difficult to separate. According to Ebert, however, are at the present in Germany populations to Timandra comae, while the sister species Timandra griseata in North Eastern Europe occurs.

Flight times and caterpillars
The Ampferspanner forms two to three overlapping generations per year. After Ebert two generations of mid-May to late June and from mid-July to early October are given for central Germany. To postpone the flight times, so that an incomplete third generation is formed in hot years.
Habitat
The Ampferspanner often occurs in more humid areas, but also in dry places. In the land of culture can be the kind of verbrachenden fields, abandoned vineyards, embankments, dams, sand and gravel pits found. Furthermore, it is almost to be found throughout the settlement area.
Way of life
The oviposition was observed on different plant parts. Crawler finds are documented in Rumex acetosa and Rumex obtusifolius, it sat the adult caterpillars on the upper leaves and the flowers and seeds of the plant. The caterpillars feed on various Ampferarten ( Rumex spp.) And Knötericharten ( Polygonum spp.):
- Hain- sorrel ( Rumex sanguineus)
- Rumex dock ( Rumex obtusifolius )
- Yellow Dock ( Rumex crispus )
- Pond dock ( Rumex hydrolapathum )
- Common Sorrel ( Rumex acetosa )
- Sheep Sorrel ( Rumex acetosella )
- Straußblütiger sorrel ( Rumex thyrsiflorus )
- Bird knotweed ( Polygonum aviculare )
- Wild buckwheat ( Polygonum convolvulus )
- Schlingknöterich ( Fallopia soon scatterbrained anica )
In the Upper Rhine Plain Falter heather ( Calluna vulgaris) and Canadian goldenrod (Solidago canadensis) were the flowers to visit (Echium vulgare), were observed. During the day, rest the butterfly with outspread wings hidden on leaves or in bushes. The characteristic merging into one another transverse fascia of the front and rear wings will dissolve the physical outline of the moth relative to its environment and provides effective camouflage ( Somatolyse ). The moths are active in the evening or on cloudy days and at night also come to light. In central Germany the winter the caterpillars of the second generation.
Dissemination
The Ampferspanner is widespread, but is rarely noticed because he lives rather hidden. In the south, reaches its dissemination North Africa, the Iberian Peninsula, the islands of the western Mediterranean over Italy and the Balkans to Asia and Turkmenistan. Furthermore, the dock - tensioner in Western and Central Europe including the British Isles, Fennoscandia, distributed in the Baltics and Russia. The sister species Timandra griseata replaces the dock clamps from southern Sweden and the Baltic States. In the east ( to Japan) added another species of this group: Timandra recompta ( Prout, 1930), Timandra paralias ( Prout, 1954).
