Ecological studies in the Norfolk Brecklands (Field & Foster, 1995; Willmer, 1985a,b) and Europe (Hamm & Richards, 1930) make this one of the best-known British aculeates.

This species is a very close relative of C. ruficornis and care is necessary to distinguish between them, particularly when identifying males.

This is a conspicuous and relatively large solitary species.

This is a very close relative of Ammophila sabulosa; in many of its sites it flies with its congener, and may be locally abundant.

This is the most common of our Oxybelus species.

Identification keys, distribution and general biology are given in Spradbery (1973), Richards (1980), Yeo and Corbet (1995), and Falk (1991).
