Adults feed on nectar from flowering plants including Datura meteloides.
....
D. meteloides contains tropane alkaloids, which are present throughout the plant including in the flowers.[5] These alkaloids have an intoxicating effects on the moth, which displays erratic flight patterns as well as uncoordinated, and often unsuccessful, landing attempts after consuming the nectar. Despite the impairment the nectar causes, the moths have been observed returning to the flowers and consuming more nectar. It has been hypothesized that the “spiked” nectar offers the moths reward beyond just nutrients.
