The Hackberry Emperor is a North American butterfly commonly found near water bodies, swamps, and in city parks or gardens. Unlike many other butterfly species, it is rarely seen visiting flowers. Instead, it seeks out tree sap, rotting fruit, and even animal droppings or moist soil for nutrients. Its erratic hopping flight and bold behavior, often landing on people, make it a distinctive and curious presence in its habitat.
