distribution within Europe
France, Iberian Peninsula, Italy (Fauna Europaea, 2007).
Also on Stachys mines Trachys problematicus, and Hering (1957a) suggests that the two might have a subspecific relationship. The distribution patterns certainly supports Hering’s idea, but the Fauna Europaea (2007) treats them as two independent species.
