Eumerus ruficornis Meigen, 1822

Schiner (1862: 362) documented this species as “pretty mean and widespread; in wet meadows (…)”. The only “recent” records dates back to 1990 (Lower Austria, Scheibbs, Schlagerboden; (1♂) leg. Franz Ressl). The host plant of the larvae is the highly-local Asteraceae Scorzonera humilis L. (Johansson 2011). Due to the extreme loss of its habitat, Eumerus ruficornis is close to extinction in Central and northern Europe (Ssymank et al. 2011; Johansson 2011).
