Hendricksons, Sulphurs, and Pale Duns (Genus Ephemerella)Observer
jerry2000Description
Sulphur dun mayfly, probably Ephemerella dorothea. Size 20. Decent hatch. Also saw one slightly darker and slightly larger dun in flight. Was that a late-blooming Ephemerella invaria?
Also fished above Route 9, 7-9PM. Same insects there, and saw a few black caddis, size 18-20 above water. Water above route 9 was 53F.
