Popis:	Insect visitors were sampled from flowers of nine sympatric tree and shrub species in the Kruger National Park, South Africa, using a landscape-scale survey approach. Two species of Terminalia L., Terminalia prunioides Lawson and Terminalia sericea Burchell (Combretaceae) together comprised 53% of the flowering trees and shrubs sampled. Scarab beetles (Coleoptera: Scarabaeidae) comprised a majority of visitors to flowers of the two Terminalia species (90% and 88%, respectively). Statistical comparisons indicate that both the composition and abundance of scarab floral visitors differ between T. prunioides and T. sericea, and between these species and sympatric flowering tree and shrub species. Individual species of Scarabaeidae show markedly different patterns of abundance: 42% were found on flowers of one tree species, 45% were found on flowers of two or three tree species, and the remaining four scarab species were common and occurred on four or more of the tree species sampled.
