context_page_description: Dryas iulia, commonly called the Julia butterfly, Julia heliconian, the flame, or flambeau, is a species of brush-footed butterfly. The sole representative of its genus Dryas, it is native from Brazil to southern Texas and Florida, and in summer can sometimes be found as far north as eastern Nebraska. Over 15 subspecies have been described.
  Its wingspan ranges from 82 to 92 mm, and it is colored orange with black markings; this species is somewhat unpalatable to birds and belongs to the "orange" Mullerian mimicry complex.
  This butterfly is a fast flier and frequents clearings, paths, and margins of forests and woodlands. It feeds on the nectar of flowers, such as lantanas and shepherd's-needle, and the tears of caiman, the eye of which the butterfly irritates to produce tears. Its caterpillar feeds on leaves of passion vines, including Passiflora affinis and yellow passionflower in Texas.
  Its mating behavior is complex and involves a prolonged courtship whose outcome appears to be controlled by the female. This raises questions pertaining to the occurrence of the evolution of sexual conflict.
context_section_description: D. iulia larvae feed on Passiflora plants almost exclusively, specifically those of subgenuses Astrophea (also known as Passiflora), Polyanthea, Tryphostemmatoides, and Plectostemma.
  As adults, male and females feed differently based on their reproductive needs. As mentioned further down, males engage in mud-puddling behavior in order to gain valuable minerals for their spermatophores. They have also been seen to agitate the eyes of caimans and turtles in order to produce tears that the butterflies can drink.  Observations of this from points 1500 km apart, were probably the first time scientific observations were coordinated via films broadcast on terrestrial television.
  Females, meanwhile, besides visiting certain flower species for their nectar – like Lantana and Eupatorium (as both male and female D. iulia butterflies do) – also use pollen from flowers to gain nutrients needed for egg production.
