Leuctra alexanderi Hanson

has been previously recorded from only 5 small cold forested creeks or spring runs in Pennsylvania ( Earle 2004b, Masteller 1996). The Pennsylvania distribution of L. alexanderi is the Potomac River basin, west and north of the Allegheny Front through the Ohio and upper West Branch Susquehanna River basins, and east to the upper Delaware River basin in northeastern Pennsylvania. Leuctra alexanderi is not as widely distributed in North America as other Leuctra species , having been confirmed from only 5 states from Pennsylvania south to Tennessee. Leuctra alexanderi is common in small spring-fed creeks in western Maryland ( Grubbs 1997).
