Most cycads engage in brood-site pollination mutualisms, yet the mechanism by which the
Cycadales entice pollination services from diverse insect mutualists remains unknown.
Here, we characterize a push-pull pollination mechanism between a New World cycad and
its weevil pollinators that mirrors the mechanism between a distantly related Old World
cycad and its thrips pollinators. The behavioral convergence between weevils and thrips,
combined with molecular phylogenetic dating and a meta-analysis of thermogenesis and …
