Adults were collected in the 1970’s by R. Surdick from Maul Spring and Powdermill Run , Westmoreland County , in southwestern Pennsylvania ; however, four years of sampling in that watershed by Grubbs (1996) did not yield any additional specimens. Only one other previous Pennsylvania record exists, from Tancascootack Creek in Clinton County ( Masteller 1996 ). Despite its rarity, benthic taxa lists for Pennsylvania streams assessments occasionally include Utaperla nymphs, which are most likely misidentifications of Alloperla usa Ricker , similar to the misidentifications discussed by Kondratieff et al. (1995) for North and South Carolina assessments. Utaperla gaspesiana ranges from Quebec and Maine south to West Virginia . New record: MONROE: (D) Pocono Creek , Camelback Road, 22 May 2002 , 1♀ (CL). Pocono Creek is a small coldwater creek in northeastern Pennsylvania .
