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.

Females of this species are readily confused with Priocnemis pusillus, P. cordivalvata and P. gracilis, although the males are readily distinguishable. Keys to species and general biology are given in Richards & Hamm (1939), Wolf (1972), Day (1988) and Falk (1991).

A very similar species - Hedychrum nobile - was recently discovered in Britain. The separation of H. niemelai and H. nobile is described in this paper

One of our most frequently encountered red and black spider-hunting wasps, perhaps because it spends a lot of time searching open sunny ground for nesting host species.

Keys and general biology are found in Sladen (1912), Free & Butler (1959), Alford (1975) and Prŷs-Jones & Corbet (1991). Until recently this species was known as Psithyrus sylvestris, but Psithyrus has now been reduced to a sub-genus within Bombus. The bee bears little clear resemblance to any of its probable host species in the Bombus pratorum group.
