Geographical distribution and occurrence
The hawkweed - syllable Owl occurs mainly in mountainous terrain, as in the Alps to 1700 meters above sea level, in the Spanish and French Eastern Pyrenees, the Caucasus and the north-eastern Turkey before. Older information about an occurrence in the Urals require confirmation. The animals from Turkey were described as ssp.elongata ( Alberti, 1969). The species is now, however, considered to be taxonomically homogeneous. It prefers moist areas and can be very limited points quite numerous occur.
Life and development
The hawkweed - syllable owl is nocturnal and also flies to artificial light sources. The females lay eggs on the food plant, from which the caterpillars hatch in August. As a food source are the leaves of low plants, where hawkweed ( Hieracium ) is preferred. The caterpillars overwinter and pupate in the spring of the following year in a white cocoon. The moths fly in one generation from June to August.
Endangering
In Germany, the species occurs only in Bavaria and is out on the red list of endangered species in the early warning. A senior figure from Baden- Württemberg is obviously based on a misidentification or a locality confusion.
