Perlodidae Klapálek, 1909

Notes

Perlodidae are commonly known as Stripetails (subfamily Isoperlinae ) and Springflies (subfamily Perlodinae ) ( Stark et al. 1998, Stark et al. 2012). This is the richest stonefly family in New York, comprised of seven genera and 28 species, including 19 Isoperla . Kondratieff (2004) and Szczytko and Kondratieff (2015) provided the most recent reviews on the Perlodinae and Isoperlinae of eastern North America, respectively. Larval identifications of Isoperla are still problematic for several eastern North American species. Beaty (2015) provided a useful photographic guide to the larvae of several species that occur in New York. Some genera of this family are commonly collected, whereas others are rarely encountered. Adult collection dates range from early March to September (Fig. 38 ). Perlodidae occupy a wide range of elevations in New York ranging from 3-1621 m asl (Fig. 39 ). Species occupying lower elevations in the state include Isoperla bilineata , I. similis , and I. gibbsae . Two species with the widest range of reported elevations include Malirekus iroquois and Isogenoides hansoni . Conversely, species with narrow ranges of reported elevations include uncommon species with few occurences (e. g., Arcynopteryx dichroa , I. gibbsae , I. lata , and I. bilineata ).
