Movie S1
Despite the fact that Arizona bark scorpion (Centruroides sculpturatus) stings are intensely painful, southern grasshopper mice (Onychomys torridus) prey on these scorpions. This video shows an adult, a sub-adult and a juvenile (respectively) grasshopper mouse attack, kill and consume a bark scorpion. Grasshopper mice may groom only briefly following a bark scorpion sting. The grasshopper mice and bark scorpions shown in this video were collected from the Santa Rita Mountains of Arizona. Interactions were staged on the morning a mouse was trapped; the mouse was monitored for approximately 10 - 12 hours following the trial and was released that evening at its site of capture.
