Most studies of the chemical ecology of plant-pollinator interactions emphasize the role of pollinator-mediated selection in shaping floral scent composition. Nevertheless, phylogeny may constrain the metabolic pathways underlying these profiles, thereby influencing the evolutionary trajectory of the emitted signals. To investigate whether phylogenetic history constrains plant chemical communication, we used the obligate fig-fig wasp mutualism. We collected floral scents from receptive figs of 3
