AbstractPollinators and UV photos of flowers ofDuchesnea chrysanthaandD. indicaare discussed. The petals ofD. chrysanthareflect UV light strongly, while those ofD. indicahave a nectar guide appearing as a spot at the base of the petals that absorbs UV light. This is the same as inPotentillawhich is closely related taxonomically. InDuchesnea, we consider the presence of a nectar guide to be a derived character. The petals ofD. chrysanthaandD. indicaare distinguished by the presence or absence of nectar guides, but both species are pollinated mostly by the same kind of pollinators, which are commonly small polylectic insects. The main pollinators are four small bees (Andrena knuthi, A. minutula, Halictus aerarius, Lasioglossumsp.) and three syrphid flies (Paragus haemorrhous, Sphaerophoria macrogaster, S. philanthus). The total number of insect visitors inD. chrysanthawas 60 species, while inD. indicathere were 51. There was no significant difference in the visitors to the twoDuchesneaspecies, therefore, the adaptive meaning of the presence of nectar guides was not determined inDuchesnea.
