Biology and notes. Dioprosopa clavata is a species with a wide distribution. It has been found visiting mainly exotic plants such as Myoporum laetum G. Forst, T. officinale, Trifolium sp., and Plumbago auriculata Lam. (R. Barahona-Segovia, pers. obs.). Also, this species have been observed visiting flowers of E. pectinatus, L. marítima, H. helix and Chlorophytum comosum (Thunb.) Jacques (Gabriela Germain, CSP records); C. ovata (Susana Delgado, CSP record); H. echioides (Mari Peña, CSP record) and Cuscuta sp. (Matías Cortés, CSP record). This species is an important biological controller of different insect pests such as aphids (Rojo et al., 2003).
Conservation status. LC; EOO = 113,098 km 2, AOO = 68 km 2, 14 subpopulations and 15 localities.
