Biology

Females are morphologically adapted to collect oil from a variety of oil-producing flowers (Iridaceae, Orchidaceae and Scrophulariaceae, Stilbaceae) in particular Diascia species (Scrophulariaceae) (Manning & Brothers 1986, Whitehead & Steiner 2001, Manning & Goldblatt 2002, Pauw 2006, Pauw et al. 2017, Whitehead et al. 2008). Flowers of Diascia species have twin spurs, which in some species are extremely elongated. Females of Rediviva species collect oil from the bottom of the spur by simultaneously inserting their elongate forelegs into each of the two spur tubes in the process pollinating the flower. The position of the anthers between the spurs ensures direct contact of pollen with the visiting bee's body. The pollen that adheres to her body makes contact with the stigma when she visits the next flower, ensuring effective cross-pollination. The oil is extracted with the aid of specialized hairs on the legs and transferred to the back legs for transport to the nest. The collected oil is mixed with pollen and this mixture is used as a food provision for her larvae, which develop in an underground nest.  Based on the correlation between spur and leg length co-evolution of the two partners as been hypothesised (Steiner & Whitehead 1990, 1991). 80% of evolutionary change in leg length was explained by adaption to the selective environment imposed by long-spurred, oil-secreting flowers i.e. long legs have largely evolved in oil-collecting Rediviva bees as a response to this selection pressure (Pauw et al 2017). These bees also have generalized pollen collecting habits (Kuhlmann & Eardley 2012) and are ground nesters (Kuhlmann, 2012).
