features

butterfly

The wingspan of the moth is 28 to 33 millimeters. The wings are light gray in the basic color and show brownish drawing elements. The intensity of the gray or brown color varies quite a lot. The inner transverse line is broadened like a ribbon towards the root, the outer one runs in an arched manner towards the front edge and is usually double. A white wavy line and a light wipe can be seen in the brownish, darkened hem area. On the hind wings there are dark transverse lines and a mostly indistinct whitish wavy line. The first abdominal segment appears in the form of a white belt. The antennae of the males are combed on both sides, those of the females are thread-shaped.

Egg, caterpillar and pupa

The light green egg shows a red and green iridescent skin and is covered on the surface with 30 wavy ribs, which also have transverse serrations. The Mikropylrosette is six to seven leaved.

Adult caterpillars are green in color and have whitish longitudinal lines.

The light brown doll is piston-shaped and has a button-shaped cremaster with a long fork tip. The wing sheaths shimmer green.

Similar species

The Ringfleck-Barkenspanner is similar to other types of bark tensioners, especially Synopsia sociaria , but differs in the rounded course of the outer transverse line.

Geographical distribution and habitat

The species occurs from the Iberian Peninsula across Europe to Mongolia and southern Siberia to Japan . In Scotland it is by the ssp , C. cinctaria bowesi , in East Asia by the ssp. C. cinctaria superfumata represented. The habitat of the species includes a wide variety of areas, for example mixed forests, bog forests, bushes, orchards , semi-arid grasslands as well as heaths, gardens and parks. The species rises up to 1500 meters in the Alps .

Way of life

In Central Europe, the Ringfleck-Rindenspanner usually forms one generation per year, the adults of which can be found from the end of March to the end of June. A second generation is trained in July and August under favorable climatic conditions. In the southern Alpine valleys, butterflies were also found in September and October. They are nocturnal and come to artificial light sources , preferably the males. Sometimes the moths appear in large numbers on the bait and have also been observed sucking on willow flowers. During the day they like to rest on tree trunks. The caterpillar feeds polyphagously on the leaves of various plants, including:

Pupation often takes place under moss on the ground. The pupa hibernates.

Danger

The Ringfleck-Rindenspanner can be found in different numbers in the German federal states and is listed in Category 3 (endangered) on the Red List of Endangered Species . In Baden-Württemberg it appears on the pre-warning list.
