Summary Although theoretical models suggest that ambush predators could have a wide range of ecological and evolutionary effects on plant–pollinator interactions, these models require predators that are both abundant and mobile. Crab spiders, the main model system for studying the effects of ambush predators on plant–pollinator interactions, are neither of these. The weaver ant O ecophylla smaragdina is a keystone predator in S outh‐ E ast A sian forests. It uses the flowers of a wide range of native and introduced species as hunting platforms for incoming pollinators. Weaver ants affect the behaviour of flower visitors and the reproductive success of their host plants. Due to their ubiquity and mobility, O . smaragdina ants satisfy the assumptions of the theoretical models. They have the potential to affect the structure of pollination networks. Synthesis . O ecophylla smaragdina in S outh‐ E ast A sia, and possibly other predatory ant species in A frican and A merican tropical forests, may play a key role in shaping the ecological and evolutionary trajectories of plant–pollinator interactions.
