Exploration of the processes that have generated current diversity and associations within this mutualism requires robust phylogenies and timelines for both the moths and the yuccas. Here we establish a molecular clock for the moths based on mtDNA, and use it to estimate the time of major life history events within the yucca moths. Colonization of yuccas had occurred 41.5?9.8 Mya, with rapid life habit diversification and the emergence of pollinators within 0-6 My after yucca colonization. A subsequent burst of diversification 3.2?1.8 Mya coincided with evolution of arid habitats in western North America. Derived non-pollinating cheater yucca moths evolved 1.26 ? 0.96 Mya. The estimated age of the moths far predates the host fossil record, but is consistent with suggested host age based on paleobotanical, climatological, biogeographical, and geological data, and a tentative estimation from an rbcL-based molecular clock. The moth data are used to establish three alternative scenarios of how the moths and plants have coevolved. They yield specific predictions that can be tested once a robust plant phylogeny becomes available.} }
