Individual show restricted distributions; for example, Chamaesphecia efetovi is documented from Crimea, Romania, Bulgaria, Serbia, and Turkey, while Chamaesphecia schmidtiiformis occurs on the Crimean Peninsula.

Human Relevance

Several Chamaesphecia have been evaluated as agents for . Chamaesphecia crassicornis was identified as the best candidate for controlling leafy spurge (Euphorbia esula) in North America due to larval survival rates on both the target weed and its European Euphorbia virgata. Chamaesphecia mysiniformis has been investigated for control of horehound (Marrubium vulgare) in Australia. Males of some species are attracted to synthetic , which has been used for and , though artificial were ineffective for Chamaesphecia schmidtiiformis.
