Named on account of its powerful and potent sting, which is said to be as painful as being shot with a bullet. The pain caused by this insect's sting is purported to be greater than that of any other Hymenopteran, and is ranked as the most painful according to the Schmidt Sting Pain Index. It is described as causing "waves of burning, throbbing, all-consuming pain that continues unabated for up to 24 hours". It lives in trees and thus can and will fall on you to scare you away from its hive--the one you didn't know was there, because it's in a tree. Before it does this, it shrieks at you. This ant, you see, can shriek.
