Remarks
Zealeuctra warreni males are easily distinguished from all Zealeuctra species by presence of the two prominent epiproct spines. The common name for this species, Early Needlefly (Stark et al. 2012[2]), is apt since its November–February emergence period is earlier compared to each of the four other regional congeners (Zealeuctra cherokee, Zealeuctra claasseni, Zealeuctra narfi, and Zealeuctra wachita) in the Interior Highlands. Poulton and Stewart (1991)[3] noted the emergence period for Zealeuctra warreni starts in November.
