of Northern Catalpa

Catalpa speciosa (Northern Catalpa)
(Bees suck nectar or collect pollen, while other insects suck nectar only; according to Stephenson, honeybees, skippers, and ants are not effective at cross-pollination; the nectar is toxic to ants and skippers, but not bees and moths; most of the moths were nocturnal visitors; except for a single observation from Fleming as indicated below, all observations are from Stephenson or Stephenson & Thomas)
