Hackberry Emperor

Fascinating facts about the Hackberry Emperor

• The hackberry emperor is rarely seen visiting flowers, an oddity for a butterfly. When it does approach a bloom it only inserts its proboscis, keeping its feet and antennae away from the petals. This behaviour means it does not pick up or transfer pollen, making it an ineffective pollinator. Such limited contact classifies it as a "cheater" that extracts nutrients without helping the plant.
• Adult hackberry emperors do not rely on nectar; instead they draw sustenance from a wide range of sources. They commonly sip the sap of hackberry trees, feed on animal waste, and even scavenge carrion such as decaying pigs, snakes and dogs. Old fruit also forms part of their diet, highlighting a highly opportunistic palate that lets them thrive where other food is scarce.
• When people walk near a hackberry emperor, the butterfly may land on the person and lick the sweat from their skin. This behaviour supplies the insect with sodium, a mineral it seeks from moist sources. By obtaining this essential nutrient from human sweat, the butterfly supplements its diet without needing to find mineral-rich plants.
• The hackberry emperor produces two broods each year, allowing every developmental stage to coexist on a single host tree. Adults lay eggs in clusters, which hatch into larvae that pupate on the underside of hackberry leaves before emerging as butterflies in early summer. Because multiple generations occur within one season, eggs, caterpillars, pupae and adults can all be observed together on the same tree at the same time.
