A very seldom collected species living in central and northern Europe (Caldara & O’Brien 1997).

In the Nature Reserve Machnatá collected by sweeping after rain on a meadow, where Erodium was not found. Larval development of the species is here probably fixed to related plant species from Geraniaceae family – Geranium sanguineum L. New species for the Czech Republic.
