2cm long body not including 2 tail filaments. brown body. light brown kegs with darker feet
2 tail filaments excludes Families Leptophlebiidae, Ephemerellidae. Two pairs of wings excludes Baetidae. This leaves Heptageniidae and Ephemeridae (National Audubon Society Field Guide). I could not count the segments in the tarsi in my photos to distinguish these two families. According to Kaufman Field Guide there are 21 Families in North America.
