Once they arrive in their breeding grounds, Painted Lady butterfly males seek out territories that have plenty of host plants capable of feeding their offspring. When a female approaches, the male takes flight and attempts to mate with her. After successful mating, the female deposits the eggs on a host plant. The hatchling caterpillars begin feeding immediately until they grow large enough to pupate and turn into an adult butterfly. When a great number of caterpillars inhabit the same area, they often form silken webs. These webs are thought to provide the growing, and vulnerable, caterpillars with some protection from predators.
