Leuctra ferruginea

Leuctra ferruginea (Walker, 1852) Notes Leuctra ferruginea is commonly referred to as the Eastern Needlefly (Stark et al. 2012). This widespread species is known from most Canadian provinces and USA states east of Hudson Bay and the Mississippi River, respectively. Further west, L. ferruginea has been reported from Saskatchewan and Minnesota south to Louisiana (DeWalt et al. 2024). This species has been reported from a wide range of stream sizes, with semivoltine life cycles in smaller streams and univoltine life cycles in larger rivers (Harper 1973 a). We reported adult collection dates from the state ranging from late April to early December (Fig. 13). We documented this species from elevations ranging from 2-866 m asl (Fig. 14) and a wide range of stream sizes, including coastal streams on Long Island (Fig. 15 d).
