Ecology

The plant is pollinated by various insects such as bees, butterflies, and skippers. The same fauna representatives also collect nectar. Bees like Melissodes vernoniae are frequent visitors to Vernonia plants in general. Another special guest the species attracts is Aphis vernoniae, an aphid that prefers to suck on juice of the species. Various caterpillars of moths also enjoy the feeding. Birds on the other hand, don't feed on it, due to hard seeds, and small amount of pollen left (for hummingbirds). Herbevorian mammals also avoid the plant due to the bitterness of its foliage.[2]
