Notes

This species is commonly referred to as the Brook Needlefly ( Stark et al. 2012). The distribution of this species is from most Canadian provinces and USA states east of the Hudson Bay and Mississippi River, respectively ( DeWalt et al. 2024). Masteller (1983) reported peak emergence of this species during mid-May from Six-Mile Creek, in Erie County, Pennsylvania. In New York, adults of this species have been reported from mid-April to mid-July (Fig. 13 View Figure 13 ). Reported elevations for L. sibleyi in the state range from 111-821 m asl (Fig. 14 View Figure 14 ). This species is common in New York, with most records to date from the Level III Ecoregions Northeastern Highlands (58), Northern Allegheny Plateau (60), Erie Drift Plain (61), and Eastern Great Lakes Lowlands (83) (Fig. 16 a View Figure 16 a ).
