Hackberry Emperor (Asterocampa celtis). A butterfly that lives in a broad swath of North America. Most of the eastern United States, central Plains states, and the southwest mountains; northern Mexico.

Its larvae survives exclusively on the many species of Hackberry trees, trees in the genus Celtis.

Hackberry Emperors over winter as larvae curled up in a Hackberry leaf, which falls to the ground in autumn becoming leaf litter. A good reason not to rake up that leaf litter!

As an adult the Hackberry Emperor Butterfly eats fermenting fruit (or corn as in this picture), dung, carrion, and sips tree sap. They also wouldn’t hesitate to sip sweat from your arm to consume the salt.
