Originally described in the genus Castnia it was later placed in the genus Geyeria ( Buchecker [1880] ). Even though three subspecies were recognized by Miller (1986 , 1995 ), they were all synonymyzed under uruguayana by Lamas (1995) . Distribution. The species is distributed in Argentina , Uruguay and Southeastern Brazil where it flies from November through February–March ( Miller 1986 ). Biology and behavior. The flight pattern is slow and hovering, atypical of most Castniidae . While individuals can be observed flying during mid-day, they occasionally fly at different times if disturbed ( Miller 1986 ). Biezanko (1961a) states that the larvae feed on Eryngium paniculatum Cav. & Dombey ex F. Delaroche (Apiaceae) . Material examined. 1 3, Castnia uruguaiana [sic] Bium.[sic], Col. F. Bourquin, Rep.
