Harvesters are a unique type of butterfly. While they may look normal with their orange and white spotty wings (see harvester butterfly picture in the comments), this species has an unusual eating habit.
Harvesters prefer to live in woodland habitats, where their favorite food lives, aphids. As a caterpillar, they have become the only strictly carnivorous caterpillar in North America. During their larval stage, they mainly eat aphids, like the beech blight aphids in this photo. To stay hidden from predatory ants, they will use their silk to empty carcasses of the aphids they have consumed to their body.
As a butterfly they continue to stray from the norms of a typical butterfly and reject nectar. Instead, they will eat the honeydew or aphid sugary secretions, and feed on mineral sources such as dung, sap and mud.
