Author's Remarks: Based on experiences in other states, I have surprisingly found very few individuals of this species in the state. I have observed one individual from the Atchafalaya Basin north of I-10, another from Hammond (Tangipahoa Parish), one from EBR, one from Black Bayou Lake NWR (Ouachita Parish), one from Tickfaw State Park (Livingston Parish) and two at Chicot State Park (Evangeline Parish).
