Grey Fox (fuscum) Ephemeroptera(Mayfly) Family: heptogeniidae Genus: stenonema Species: fuscum Common Name: Grey Fox Important Statistics Size: 12-14 mm Water Temp: Hook: #10 2x long Emerging: Sporadically all day Hatch Date: Early June (Catskills) Habitat: Fast moving water SPECIES LIFE STAGE HOOK BODY COLOR WING COLOR TAIL COLOR fuscum dun 10 2x light medium gray mediuim gray fuscum spinner 10 2x fuscum emerger 10 2x Grey Fox Comments: Nymph Nymphs move from their fast water habitat to adjacent slower shallows. A weighted nymph fished on the bottom with motion is effective until the hatch begins. During the hatch, use an unweighted nymph fished in the surface film. Emerger Fish in the surface film during early hatch. Dun As with vicarium, fuscum duns float long distances trying awkwardly to get off the water. Flyfishers should locate feeding trout and float their imitation over the feeding station in the attitude of naturals. Spinner Keep watch above for gathering spinners and get ready for the action. Choose a position near fast water and note the best targets as much of the spinner fall occurs after dark. Fish a full spent fly dead drift.
