oa Journal of the Entomological Society of Southern Africa - Resin collection and the pollination of Dalechampia capensis (Euphorbiaceae) by Pachyanthidium cordatum (Hymenoptera: Megachilidae) in South Africa
We report the collection of resin and pollen from the inflorescences of Dalechampia capensis Spreng. (Euphorbiaceae) by Pachyanthidium cordatum (Smith) females. Bees in this tribe of Megachilidae, while known to collect floral resin in the New World, have not previously been observed collecting it in the Old World. Size and behaviour of P. cordatum suggests that it is an effective pollinator of D. capensis, but the close proximity of staminate and pistillate flowers does not preclude self-pollination or pollination by generalist pollen collectors.
