Ostrocera nymphs

are rarely collected during routine water quality monitoring; however, they can be common in small acidic, often intermittent creeks and spring runs ( Earle 2004b). Adults can also be collected alongside small to medium cold water creeks, presumably emerging from nearby springs or seepage areas. The most common Pennsylvania species is O. albidipennis (Walker) .
