Author's Remarks: I have trapped a few of these from ponds in Kisatchie National Forest (Natchitoches Parish) in 2012, and dipnetted a couple juveniles from Lake Martin (St. Martin Parish) in 2015. In addition, they would often be caught as bycatch in some subpar sites while trapping for Gulf Coast Waterdogs in Southwest Louisiana. A juvenile was dipnetted from Stuart Lake in Kisatchie on the winter LARE field trip in 2018.
