As nocturnal creatures, you will not often find bark scorpions to be active during the day. They prefer to hunt at night, giving them protection from extreme heat. Bark scorpions can become vicious when hunting. They lie in wait and use the small hairs on their legs and underside to sense their prey when it comes near. Their pincers, or pedipalps, are fairly weak, so the scorpions must rely on the potent venom from their barbed tail to paralyze the prey before grabbing it with their pincers. Bark scorpions primarily eat cockroaches, spiders, moths, and other similar invertebrates.
