Thankyou for your wonderful website! We were able to indentify this beautiful giant centipede we found outside our front door yesterday. It was approx 5 1/2 " long! We managed to put it in a cup and move it safely, away from our house. Giant redheaded centipede, Order: Scolopendromorpha, Family: Scolopendridae, Genus and species: Scolopendra heros Girard.
Thanks for the image and information. We wish you had provided us with a location, but we are guessing it is probably Oklahoma or Texas.
