Army ants are superefficient in their retrieval of prey. There are four distinct worker castes in Eciton burchellii each important to the high efficiency of foraging. When prey is too large for an individual it is segmented by workers into manageable pieces then conveyed to the bivouac. Workers carrying prey were collected to determine the relationship between prey size and the worker(s) carrying prey as well as examine prey as an evolutionary pressure for selection of the submajor caste. Results show length and width are poor determinants of which caste is performing the retrieval task, as all castes are equally as likely to carry prey of any size. Prey biomass was shown to be a significant factor in determining which caste carried ...
