The clematis window spot ( Thyris fenestrella ) is a butterfly of the window spot family (Thyrididae). It is the only species of this family in all of Europe .
features
The moths reach a wingspan of 12 to 15 millimeters. They have dark brown colored wings that are patterned with reddish brown and yellowish spots. In the middle of all four wings two whitish, slightly translucent window spots can be seen, with those of the rear wings being larger.
The caterpillars are about 10 millimeters long. They are olive green with a slight reddish tint, their skin is slightly transparent and have a dark brown head. There are numerous large, black spots on the body.
Occurrence
The animals are rare in the south of Germany , but not at all in the north. They live on moist and warm forest edges , preferably near water and in the mountains.
Way of life
The very shy moths are rare and mostly found with only a few animals in their habitats. They are found in the approach to flowers, especially on water fishes ( Eupatorium spec. ), Privet ( Ligustrum spec. ) And umbellifers (Apiaceae).
Flight and caterpillar times
The moths normally fly in one generation per year from May to October, but in warm places a second generation can be formed within this time. The caterpillars live from July to August.
Food of the caterpillars
The caterpillars feed exclusively on clematis ( Clematis vitalba ), but probably also on other clematis species .
development
The females lay their reddish eggs one by one on the edge of the fodder plant leaves. The caterpillars that hatch from it cut the leaflet diagonally towards the middle and roll up the resulting triangle in order to live in this dwelling. They build a new roll of leaves after each molt. Finally, a whole leaflet is rolled up. These dwellings are not noticeable on the plant because they are directed downwards. But if you pick up a "tendril", you will recognize it immediately. They pupate in a cocoon on leaves and in hollow stems or other niches.
