Abstract
Large hovering flies with elongated nectar-feeding mouthparts play an important role in the pollination of South African plants. Here we describe and illustrate the pollination of two long-spurred orchids —Disa oreophila H. Bolus subsp.erecta Linder andBrownleea macroceras Sond. — by the long-proboscid flyProsoeca ganglbaueri Lichtwardt (Nemestrinidae).
