Author's Remarks: I have only observed this species alive a handful of times in Louisiana. The first was a very large individual in 2011 sunning on a slope in Chicot State Park (Evangeline Parish). In 2017 a group of us found two in one morning in West Feliciana Parish. In early 2018, a group of us found a large individual in New Orleans East, and a bit later another group of us found one in West Feliciana Parish. On the LARE field trip in the summer of 2018 to Chicot SP, we found a large adult. I found two dead on the road, one each in 2012 and 2018, on Longleaf Vista Road in Kisatchie National Forest (Natchitoches Parish). We found a beautiful adult in the woods near the trail at Mary Ann Brown Preserve on a LARE on-your-own field trip during the pandemic in August 2020. We also found one hit but alive on Castor Plunge Road near Woodworth in 2021.
