Cheiracanthium punctorium, one of several species commonly known as the yellow sac spider, is a spider found from central Europe to Central Asia. They reach a length of about 15 mm, and their bite can penetrate human skin; the bite has been compared to a wasp sting, perhaps a bit more severe, although susceptible persons can have stronger reactions, like nausea.
