oa Journal of the Entomological Society of Southern Africa - Reproductive abilities of orphaned workers of two ponerine ant species (Hymenoptera: Formicidae)
Workers of Pachycondyla caffraria and Megaponera foetens could lay eggs in the absence of a queen, but only those of P. caffraria hatched. The larger a worker of M. foetens was, the more likely it was to lay eggs, and the more eggs it was likely to lay. The relevance of these findings to understanding the evolutionary origins of the loss of the queen caste in related species is discussed.
