Euarestoides dreisbachi Foote

Distribution. Mexico (Chiapas, Distrito Federal, Durango, Guanajuato, Hidalgo, Jalisco, Michoacán, Nayarit, Oaxaca, San Luis Potosí, Sinaloa, Sonora, Veracruz, Zacatecas) and Guatemala. The specimens that formed the basis for the range of this species indicated by Norrbom et al. (1999), other than the specimens listed by Foote (1958), are listed below.

Biology. Foote (1958) listed the name “ Baccharis glutinosa ” with the data for a male paratype from San Juan del Rio, Durango, Mexico without indication whether the specimen was collected on or reared from this plant. This presumably refers to B. glutinosa auct., which = B. salicifolia (Ruiz & Pav.) Pers. , and not B. glutinosa Pers. , which does not occur in this part of Mexico. We have reared E. dreisbachi from B. salicifolia in Guatemala, confirming its status as a host. The larvae feed in the flowerhead. Flies were either reared from or collected on B. salicifolia in Mexico. A single female was swept from Baccharis neglecta Britton by Paul Boldt in Mexico, but it is unclear if this plant is also a host.
