Which scorpions can hurt you
Official sources single out these scorpions in Oklahoma, in their own words:
Painful sting. “This scorpion can inflict very a painful sting, but it is not considered as potent as some of its relatives. It probably has a minor medical significance for healthy humans.” Oklahoma State University Extension, School IPM program
The one scorpion on the list
Venomous species first, then A to Z. Do not handle them.
“This scorpion can inflict very a painful sting, but it is not considered as potent as some of its relatives. It probably has a minor medical significance for healthy humans.” Oklahoma State University Extension, School IPM program
Size
Usually about 2.5 inches. Sources range from 1 to 1.5 inches on average (Missouri Department of Conservation) to up to 3.5 inches (Oklahoma State).
How to recognize it
Slender pincers and a long, slender tail. The tail is longer on males than females.
Tail ends in a stinger, usually carried up and over the body.
Venom: “The most common species found in Oklahoma is about two inches long. … The venom can produce considerable pain around the area of the sting, but swelling is generally limited. … The sting of the species of scorpion we have in Oklahoma is not considered to be lethal and rarely causes few problems.” (Oklahoma Cooperative Extension Service, Oklahoma State University)
Habitat: Scorpions generally hide during the day and are active at night. They tend to live under boards, stones, or other objects; or beneath loose bark on trees and logs. (Oklahoma State University Extension)
