The Harvester is found almost entirely in woodland habitat. It is unique among butterflies in that its larvae are carnivorous and feed upon woolly aphids. Prior to 2005, I had seen this species only four times, all close to water, and the individuals were either sunning themselves or getting nutrients from scat.
