Advertisement A female H trilineatus tagged me on the shoulder. I was showing one of my friends me handling her. As I tried to get her back in a deli cup, she made her way up to my shirt sleeve. I got kinda freaked out and told my friend to get a piece of paper and slide it under her while I had the deli cup over her so she couldnt get to my face (she was close!) When he slid it under, she tried to sting it, went straight through the paper and my shirt. She was maybe 2" at the time. I did not get any medical attention. Just tried to relax my arm and resist from massaging the sting. Ice pack worked well for a short time. I had pain from my upper neck, my whole arm and hand, and all the way down to my waist on the right side of my body. Horrible throbbing pain for a total of five hours. edit: on a scale from 1-10 (5 being a wasp sting) id say this was a 9. Could have been much worse.
