Male Cinygmula mimus Mayfly Spinner
View 2 PicturesMale Cinygmula mimus spinner trapped in its subimago (Subimago: Mayfly nymphs emerge from the water into subimagoes, better known to anglers as "duns." They are a sexually immature, winged, recognizably adult stage and they must molt one more time into imagoes or "spinners" before they can mate.) skin, a cripple (Cripple: In fly fishing, a cripple is any insect which has been injured or deformed so that it cannot escape the water. This may include stillborn emergers or fully emerged adults which have been damaged, often by wind or waves, so that they can no longer fly. Trout often favor eating crippled insects.)?? Male Rhithrogena robusta Mayfly Spinner
View 3 PicturesThese specimens were collected from a mating swarm from the east branch of the North Fork of the Touchet River, upstream from the Bluewood Ski Area turn.It was a sunny warm day, mating swarm as 4-8 ft. above this small stream. Four male spinners were collected.Stream photos were taken. Epeorus deceptivus Mayfly Nymph
View 4 PicturesIdentification notes from the microscope: Gills on segment 1 extend anteriorly below the body, but not all the way to touching; posterolateral spines minor; femora (Femur: The main segment of an insect's leg close to the body, in between the tibia and the trochanter.) without fuscous macula. Male Tricorythodes (Tricos) Mayfly Spinner
View 3 PicturesI collected these males about 9:30 AM, air temp. about 68 degrees F. The males were flying about 3 ft above the stream flying up and down the stream rather than the typical vertical swarm you see with most mayfly males. The males are black and the females are a green color due to the eggs they are carrying. They do not live very long which is typical for small bodied mayflies. They do not fly during windy conditions. I suspect these are Tricorythodes minutus.
