This is the larger of the two species of British mutillids (the other being Smicromyrme rufipes). Unlike many aculeate wasps, the female is apterous, a feature which gives it an ant-like appearance, and leads to its being called a 'velvet ant'. The male, however, is fully winged and capable of sustained flight.

Identification keys, distribution and general biology are given in Nielsen (1932), Spradbery (1973), Richards (1980), Falk (1991), and Yeo and Corbet (1995).
See Symmorphus crassicornis for literature on this species.
A small black solitary wasp. Identification keys are given in Yeo & Corbet (1995), Lomholdt (1984) and Richards (1980).When using Yeo & Corbet (1995) or Richards (1980), it should be noted that Crossocerus congener (Dahlbom) has recently been added to the British species list. C. congener is very similar in appearance to C. podagricus but has only been recorded on a very few occasions. Critical determinations for C. podagricus are best made using Lomholdt (1984).
