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