摘要：

We report the establishment of two representatives of a new ecological functional group on the sub Antarctic island of South Georgia pollinating insects in the form of the hoverfly Emistahs croceunaculata Jacobs (Diptera Syrphidae) and the blowfly Calliphora a mum Robineau Desvoidy (Diptera Calliphoridae) The floricolous adults of these two species provide a new ecological role pollination in the ecosystems of this island The activity of their respectively saprophogous or necrophagous larvae will also augment that of the native insect and microarthropod soil fauna We discuss the potential new synergy between this functional group and that of a number of established non native plants reliant on insect pollinators for successful seed set and hence dispersal that are currently of persistent status with very limited local distributions
