Collections of diurnal insects from a population of Phlox bryoides on shortgrass prairie in southeastern Wyoming showed the flowers to be visited predominantly by Synhalonia fulvitarsis, a long-tongued bee. Analysis of pollen loads carried by captured bees revealed that almost all individuals were collecting Phlox pollen. P. bryoides may be an exception to the generalization that the genus Phlox is exclusively pollinated by Lepidoptera.
