Biological notes. Isoperla montana is the most widespread species of the I. montana Group occurring from New Brunswick, Canada to North Carolina and west to Indiana ( Szczytko & Kondratieff 2015). The majority of Virginia records are from the Ridge and Valley Physiographic Province with few records east of this province, particularly in the southern part of the state. Szczytko and Kondratieff (2015) reported I. montana from North Carolina based on two females collected by the authors (CJV, BCK). As noted above, species determination of isolated females is difficult, especially in the southern Appalachians where the ranges of I. montana and I. kirchneri overlap, as such this record should be regarded as tentative. In addition to the material listed above, we also examined specimens of I. montana reported by Grubbs (2016) from Alabama. These specimens appear to represent an undescribed taxon based on details of the aedeagus and ovum, but more specimens with the aedeagus everted and mature ova are needed for confirmation.
