Coexistence of Three Species of Desert Scorpions by Habitat Selection

The scorpion fauna in Southern Arizona is very rich in both diversity and abundance, but its ecology is poorly understood. This is especially true in the Tucson area. My aim is to understand the strength and importance of habitat selection, as a mechanism, in the organization of a desert scorpion community.


Scorpions in Arizona feed on a variety of foods. They eat a variety of insects, spiders, small mice, lizards, and other scorpions. They can live without food for months and need water to survive. In Arizona, the giant hairy scorpion lives in the Saguaro Forest and feeds on centipedes, spiders, and other scorpions.

During hunting, scorpions use their forceps to prey on their prey. They also use their stings to inject neurotoxic venom into their prey, paralyzing it and allowing them to feed without much resistance. Scorpions can crush their prey with their tricks, but don’t need barbs to sting small insects.


In Arizona, scorpions become active during the summer months causing them to stay indoors during hunting. During feeding, the scorpions do not absorb solids, but take in fluid from their prey. They have a sharp claw-like mechanism that extends from their mouth and pulls a small portion of prey out, allowing them to feed on it.

If symptoms worsen within 1-4 hours of being stung by a scorpion, you should go to the emergency room as soon as possible. Sometimes the sting of scorpions can lead to death. If the sting leads to death, it usually occurs in people who are older than 6 years.

Scorpions are nocturnal predators which means they are active at night and spend time hiding in things like rocks, wood studs, house corners and carpets.

WARNING: DO NOT put your body, feet or hands under these items without checking for scorpions first.

Scorpions should never be treated unless they are annoyed or easy to handle.

The venom of scorpions is a neurotoxin, a chemical that affects the nervous system and can kill or paralyze its prey. Their stings are extremely painful, and the venom is strong enough to cause severe reactions among allergy sufferers. Some of the stings come from people putting feet in shoes, folding clothes after clothes sitting overnight around the house or outside, grabbing moving boxes, moving furniture, sitting on scorpion accidently, stepping on one while gardening, etc.

    Scorpions have discovered that moisture is the protection they need in our courtyards and homes. Tall grasses, gardens, overgrown gardens, trees, mulch, and debris provide abundant food and habitat for insects and scorpions. But when it gets hot and dry, scorpions migrate in search of moisture. Because scorpions live in desert conditions, they need water sources and cool areas to survive.

    Scorpions feed on other insects such as crickets, spiders, scorpions, cockroaches, and centipedes. Many insects, spiders and other prey attract predators such as scorpions. Scorpions, especially in large numbers, are a huge problem. You can spray your property with other pesticides to prevent it from becoming a scorpion feeder ground.

    Ants, spiders, cockroaches, locusts, and general pests will not keep scorpions away. The best way to prevent spiders from entering your home is to secure your home, seal it and have a black light for hunting; the black light is shown on the scorpion and its body illuminated.
