Parasitic biology

Its host is probably a eumenine wasp. Morgan (1984) gives Ancistrocerus trifasciatus as a host, and it has also been reared from this host by Mike Edwards (pers. comm.). Niehuis (2000) gives Symmorphus bifasciatus quoting rearing evidence, and S. connexus. The distribution of C. angustula in Britain is similar to both A. trifasciatus and S. bifasciatus.
