Predators inflict high mortality on the four species of wasps associated with the fig Ficus pertusa L. in Monteverde, Costa Rica. Because one of these wasps is the obligate pollinator of the fig, predation may have a strong impact on successful pollen donation by the plant. The natural histories of several predators are described: an ant that feeds on wasps arriving to oviposit, moth and weevil larvae that destroy wasps as they develop within the fruits, a staphylinid beetle that feeds on mature wasps before they leave the fruits, and a group of birds that gleans wasps as they leave. The synchrony of arrival and departure of pollinators from the fig trees probably make them the species least vulnerable to predation.
