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 belong in once the human owners no longer wishes to keep them. This may explain sightings outside of their native and natural range (Southern California and Arizona).
