The pollination patterns of bees and butterflies were observed in an assemblage composed of 57 plants of Lythrum alatum and 30 plants of L. salicaria. Lythrum salicaria was preferred by both groups of pollinators as indicated by the greater number of flights from this species as compared to flights from L. alatum . The degree of assortative pollination was measured in both groups of pollinators and was greater in bees. Fidelity in bees appeared to be in response to species attractiveness, whereas in butterflies it appeared to be in response to species balance.
