The caterpillars are about 10 mm long. They are olive green colored with a slight reddish tinge, with their skin is slightly translucent and have a dark brown head. On numerous larger body, black spots are distributed.
Occurrence
The animals are rare in southern Germany, in the north, however, not before. They live in warm, moist forest edges, preferably near bodies of water and in the mountains.
Way of life
The very shy moths are seldom and usually occurring with only a few animals in their habitats. They are found in the flowers approach, ( Eupatorium sp. ) Especially on Wasserdost, privet ( Ligustrum sp. ) And umbelliferous plants ( Apiaceae ).
Flight times and caterpillars

Food of the caterpillars
The caterpillars feed exclusively on Real Clematis (Clematis vitalba ), but probably also from other Clematis species.
Development
The females lay their reddish eggs one at the edge of the feed plant leaves. The resulting hatching caterpillars cut the sheet slanted towards the middle and roll the resulting triangle in order to live in this dwelling. You build up after each molt a new sheet roll, finally a full sheet is rolled up. These dwellings do not fall on to the plant, as they are directed downwards. But you raise a tendril on, you can see them immediately. They pupate in a cocoon of leaves and hollow stems or other niches.
