Pollinator Web: Arizona Bark Scorpion

Observing the cast of characters that comprise the pollinator web ecosystem in the low desert in Phoenix Arizona.

Although this scorpion does not seek to attack humans, it will sting if threatened, especially if its young are threatened. The bark scorpion is able to climb vertical surfaces that are sufficiently rough, and can enter a dwelling through cracks as small as 1/16″. They are nocturnal and can be found under rocks, wood piles or bark, as well as on rock walls or in trees.

Arizona Bark Scorpion (Centruroides sculpturatus)

The Arizona bark scorpion is the most venomous species in North America; potent enough to cause severe symptoms, such as severe pain, numbness and vomiting in adults.

But of course, the Arizona bark scorpion plays a critical role in the ecosystem, as both predator and prey. They consume beetles, spiders, crickets, cockroaches, other insects and other scorpions. And they are a food source for pallid bats, birds (especially owls), reptiles, spiders, snakes, peccaries, rodents and other scorpions.

The pollinator web ecosystem is well balanced, and even characters that we may find scary have their place.

    Very interesting information. I didn’t know scorpions were food for so many.

      Agreed! Every player has at least one important role to play in the pollinator web ecosystem 🙂
