Eupithecia impurata (Hübner, [1813])

Eupithecia impurata: Adult (e.l. Bregenzer Wald, 2010) [S] Eupithecia impurata: Young larva (Bregenzer Wald, Kanisfluh, W-Austria, late July 2010) [M] Eupithecia impurata: Young larva (Kanisfluh, July 2010) [M] Eupithecia impurata: Larva (Kanisfluh, July 2010) [M] Eupithecia impurata: Larva (Kanisfluh, July 2010) [M] Eupithecia impurata: Pupa [S]

Host plants:
The caterpillar lives on Campanula species on rock, particularly Campanula rotundifolia, C. cochlearifolia etc.

Eupithecia impurata inhabits sunny to semi-shaded locations on rocks (often in the open forest zone) or near-natural walls of rock. In Vorarlberg (west Austria), I found young caterpillars in late July 2010 at the foot of the Kanisfluh on a street accompanying wall.

Life cycle:
Eupithecia impurata hibernates as a pupa. The moths fly from June to mid-August. The caterpillars live from July to September and can be tapped so that you can keep one hand under the plants and the other shaking the plants.

Endangerment: strongly endangered

Endangerment factors:
Eupithecia impurata is endangered on smaller rocks outside the Alps by shadowing due to rising woods, by sport climbing or street widenings. In the Alps, the risk is still lower.

Eupithecia impurata occurs locally in Europe in the mountains (Alps, Swabian Alb, Pyrenees etc.). The moth misses in the north.
