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.
This species is widely distributed throughout the British Isles, with only a few records from north of Yorkshire. There are several records from Ireland (Wexford and Wicklow).
Widespread in northern and central Europe, and in south European mountains. Also occurs in Central Asia and the Nearctic (Wolf 1972).
