    Western Short-horned Walkingstick - (Parabacillus hersperus)

    Their antennae may seem long to the human eye, but compared to other Stick Insects, the Western Shorthorn Walkingstick is below average.

    Staff Writer (8/24/2017): Walkingsticks, or Stick Insects, are long, non-flying, non-jumping insects that resemble tree sticks and twigs. This camouflage allows them to feed on plant material mostly undisturbed by predators. The Western Shorthorned Walkingstick is all of these things. Its antennae can be mistaken for another set of legs. They stretch out from the head and are about twice the length of the head region. Other Walkingsticks have antennae that are longer in proportion.

    This species can be found in dry, arid regions in the summer and autumn. Look for them on in chapparal and open fields where they can be found feeding on the foliage of globemallow, deerweed and other native plants. It is not unusual to spot them clinging to windowscreens and on walls. They may drop to the ground and pretend they are dead if threatened.

    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.
