is the type species of the genus Fidelia
(Friese 1899, Brauns 1905). It is a robust, hairy, fast-flying, solitary bee that inhabits arid regions of southern Africa. In this habitat rainfall is largely limited to the winter months while summers are hot and dry. F. paradoxa
fly from early spring to summer (August to February), collecting pollen from flowers of herbs, mostly in the ice plant family Aizoaceae
(Rozen 1970, Whitehead 1984, Whitehead and Eardley 2003). Unlike most other bees in the area they remain active after the spring floral flush and may play an essential role as pollinators of later-flowering plants (Whitehead and Eardley 2003). Nests are build in burrows in the ground. Females have particularly long hairs on the ventral side of the abdomen, which function as a pollen-carrying apparatus (scopa). The hind legs also have scopa-like hairs, but these are not used to carry pollen (Whitehead and Eardley 2003).
