    Arizona Desert Scorpion - (Hadrurus arizonensis)

    The hearty Arizona Desert Scorpion is comfortable in one of America's driest regions and can grow bigger than the palm of an adult's hand.

    Staff Writer (8/7/2017): The Arizona Desert Scorpion is largest species of scorpion known in the United States. Like most scorpions, it is nocturnal, coming out mostly at night for feeding and mating. During the day, they usually burrow in loose soil or under rocks for shelter. Also like all scorpions, it is venomous, though a sting from this species will only produce a great deal of pain in the wounded area and it not considered life-threatening. That said, small children and the elderly tend to suffer more from a sting so seeking medical attention afterward may aid in pain relief.

    To reproduce, the male and female appear to dance together. The male drops a sperm packet on the ground on the female picks it up to fertilize her eggs. Soft-bodied instars (young scorpions) are born alive, not hatched from eggs. They climb on the mother's back and will reside there for almost 2 weeks without eating while they molt and become harder. Afterward, they will venture on their own, hunting for insect prey.

    The stinger of a scorpion is used to immobilize insects, spiders, centipedes, or even tiny lizards. The scorpion then uses its claws to rip the prey apart. They then proceed to suck out the body fluids as a meal.

    The Arizona Desert Scorpion has been kept as a 'pet' and can have a long life in captivity, though it will unlikely reproduce under such conditions. It is possible that disenchanted 'pet owners' have released their scorpions in areas they do not naturally occur in once the owners no longer wish to keep them. This may explain sightings outside of their native and natural range (Southern California and Arizona).

    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.
