    Hackberry Emperor - (Asterocampa celtis)

    The warm weather of the southern U.S. and Mexico allows the Hackberry Emperor butterfly to produce up to three generations in just one year.

    Staff Writer (8/2/2016): Hackberry Emperors can be found near hackberry trees. The larval caterpillars feed on the leaves of this host plant and namesake. They also feed on sugarberry trees. Many of them may be found feeding in close proximity to each other because females lay fertilized eggs in clusters on leaves. Caterpillars are plumpy and green with two yellow stripes running down the dorsal side (back). Yellow dots from head to rear may be visible between these two stripes. White diagonal lines on the sides of the caterpillar also run from head to rear. The green body is freckled with tiny white spots. Two fleshy antennae extend from the head and split into short fleshy branches. The tip of abdomen splits into a nubby two-pronged 'tail'.

    Adults can vary in color and can range from brown to orange. They are fast and erratic in flight and rest on tree trunks head-down. They feed on rotting fruit juices, tree sap and animal dung. They may also visit decaying animal carcasses for liquid nourishment. Look for adult Hackberry Emperors in forests, woodland edges, near water sources (creeks, rivers, streams), gardens and backyards.

    BUGFINDER: What Kind of Bug is This...
    BUGFINDER allows for a quick search of the Insect Identification database by selecting primary color, secondary color, number of legs and the territory / state in question. If only one color is present on your insect, select it again as its SECONDARY color. Remember that the more details you can offer, the better your chances of finding a match. As a rule of thumb, six legs are typical for most insects whereas spiders generally have eight legs.
