Perlinella drymo (Newman)

is the less commonly collected of the two Pennsylvania species of Perlinella . Both adults and nymphs are extremely elusive. Only two previous Pennsylvania adult records exist, one from Northampton County in 1931 and one from Cumberland County in 1949 ( Masteller 1996). Perlinella drymo is a widespread North American species found from the Canadian Maritimes south to Florida and west to Minnesota and Texas.

New records: LUZERNE: (S) Nescopeck Creek, old foot bridge at lower end of Nescopeck State Park, 20 April 2001, 1 nymph (MW); MONTGOMERY: (D) unnamed tributary to Schuylkill River near Spring City, 9 February 2005, 1 nymph (MB). Based on these records, P. drymo appears to prefer smaller cooler creeks than P. ephyre (Newman) , which inhabits large warm water creeks and rivers in Pennsylvania.
