Biology and notes. Eristalis croceimaculata is the most austral flower fly species in the world. It reaches Navarino Island, the furthest southern island in Chile. Recently, it was recorded in South Georgia Island in front of the Antarctic edge (Chown & Convey 2016). Before the revision of the Neotropical Eristalis species, the name E. bogotensis (Macquart, 1842) was used for a wide-range of species from Colombia to Tierra del Fuego (Wakeham- Dawson et al., 2009). Thompson (1997) showed that the name E. bogotensis, used to designate a species that occurs in Colombia, Ecuador and Peru, was actually used for two different species. Southern specimens (occurring in Argentina and Chile) were erroneously identified as E. bogotensis, but they were E. croceimaculata. This species has been recorded visiting flowers of Berberis sp. (Fernando González CSP record), T. officinale (Benjamín Silva CSP record); Bidens aurea (Aiton) Sherff (Francisco Espinoza, CSP), and Malus domestica Borkh (Vanessa Durán, Paz Gatica, Ignacio Montenegro and Rodrigo Barahona-segovia, pers. obs.). Conservation status. LC; EOO = 669,477 km 2; EOO = 108 km 2 and 28 localities (or subpopulations).
