Ecology

In Turkey, it lives in the mountains, usually at heights between 900 and above sea level. It has, however, been found as high as 2855 m.

Its major food sources are flowering plants from the Boraginaceae (forget-me-not family), Asteraceae (aster family), Lamiaceae (mint family), and Fabaceae (pea family).
