Widespread in North America, especially the southern states, the Hackberry Emperor is often viewed by children as a "friendly" butterfly because of its propensity to land on visitors to the margins of a woods. This reflects the fact that it is not primarily a nectar drinker, adapted instead to obtaining water and nutrients from rotting fruit, tree sap, dung, carrion, and... human sweat.
The photos show a Hackberry Emperor on the ground, on a forearm, and on my jeans, taken during the
SWBA field trip to Cherokee Marsh a couple weeks ago. (The apparent color variation is I think more likely a reflection of the available light at the time the photos were taken.)
