Chamaesphecia
Spuler, 1910
Chamaesphecia is a of () established by Spuler in 1910, containing over 80 distributed primarily across the Palearctic region. Species are characterized by their -mimicking appearance and specialized larval associations with plants, particularly in the Euphorbiaceae and Lamiaceae. Several species have been investigated for of weeds, including leafy spurge (Euphorbia esula) and horehound (Marrubium vulgare). The genus is divided into two subgenera: Chamaesphecia and Scopulosphecia.

Distribution
Palearctic region, with highest diversity in Europe, Russia (including Crimea, Volgograd Region, Stavropol Territory, Northern Caucasus), Central Asia, and extending into Turkey and the Balkans. 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.
