Abstract

Bees did not perform exactly as the marginal value theorem predicted they should to maximize their rate of net energy intake, which strongly implies that optimal foraging models which predict a shift in any particular behavior in response to environmental conditions are too simplistic to accurately predict foraging behavior.
