Multiple occurrences of mutualism in the yucca moth lineage

摘要: The complex mutualism between yuccas and the moths that pollinate their flowers is regarded as one of most obvious cases coevolution. Studies related genera show at least two critical behavioral life history traits suggested to have resulted from coevolved in yucca are plesiomorphic family. Another trait, oviposition into flowers, has evolved repeatedly within One species with these traits, Greya politella, feeds on pollinates plants a different family, but pollination occurs through component behavior than moths. Major differences compared hosts G. politella only passively its host copollinators often contribute pollination. This analysis suggests evolution may required few changes truly features this interaction appear be active by moths, associated morphological structures for carrying pollen, exclusion yuccas.
