Geographical distribution and occurrence
The Great Rock Bind tensioner is to find gaps in the mountains of central and southern Europe. In the Alps, he comes in front of heights up to 2200 meters. It inhabits rocky mountain and mountain landscapes preferred, gorges and scree.
Way of life
The moths fly at low altitude levels in two generations in the months of May to July and August to September, at medium and high altitudes in a brood from June to August. However, the majority of hatched in late summer moths of the supposed second generation come from übersommerten caterpillars cocoon themselves after hibernation in the spring. During the day, they like to rest on rocks or stones. At night they visit artificial light sources. The caterpillars feed on various Labkrautarten ( Galium ), and include: White bedstraw ( Galium album ), forest - bedstraw ( Galium sylvaticum ), Shiny Meadow bedstraw ( Galium lucidum ) or Lady's Bedstraw ( Galium verum). Whether they are in the field also Meier species ( Asperula ) assume still requires confirmation. The caterpillars pupate in a slight cocoon on the ground. The species overwinters as a caterpillar.
Endangering
The Great Rock Bind tensioner comes in Germany in Bavaria as a kind of geographical restriction ago and is in Baden- Württemberg as endangered.
