This genus is known for the infamous D. occidentalis and D. klugii, which are known for their very large size (nearly 1 inch) and painful sting. These two species rank a 3 out of 4 on the Schmidt sting pain index. However, members of this genus are highly variable in sting intensity. In contrast, the petite D. thestis only ranks a 1.(2)
