Author's Remarks: I have found this species at multiple locations within Lafayette Parish, including the cities of Lafayette and Youngsville. In one woodlot near the mall in Lafayette Parish, this species has become very abundant - multiple cover objects turned over in a 2012 outing contained up to 5 or 6 individuals. This species has now been detected in the Atchafalaya Basin in 2014 in the Indian Bayou area in St. Martin Parish. I also found an individual in Sherburne WMA on Bayou Manual Road in 2019.
