Researches nectar production and pollination of Asclepias verticillata. The most frequent visitors were hasps, honeybees, moths, and the cabbage white butterfly. However, most visitors were nectar thieves and did not carry pollinia. This may explain the low percentage of fruit (pod) set in this species.
