One of three large species of Priocnemis with plentiful erect hair on the face and propodeum (subgenus Umbripennis). P. perturbator is often found at the flowers of Wood spurge, Euphorbia amygdaloides, in woodlands during May. Identification is given in Day (1988). Many early records for this species may be confused with those for its close relative P. susterai Haupt.
Widely distributed throughout Britain and Ireland.
Widespread in central and northern Europe and Asia eastwards to Japan (Wolf, 1972).
