My minnow trap held more than minnows today. This is one of the waterscorpions, a predatory true bug that hangs out in the water. This one appears to be of the genus Ranatra, but I can't get it down to species based on the picture. There are records of at least seven species of this genus in NC. I probably could have pickled it and sent it off to NC State for an ID, but I didn't feel like killing it. Sometimes I don't have to know... By the way, should you come across one of these, please handle carefully. They can bite!
