Green Mays
This common name refers to only one species.
These are very rarely called Green Mays.
Ephemera guttulata's size, numbers, and hatching characteristics have made it a favorite of fly fishermen since the sport first came to our waters.
It is on par with the Midwest's
Hexagenia limbata hatch for its ability to lure huge
piscivorous (Piscivorous: Anything which eats primarily fish is a piscivore.) brown trout to eat insects at the surface once a year. The special charm of the Green Drake hatch is that it often takes place during pleasant Spring afternoons. It can be challenging because the large flies are easy for trout to inspect in the daylight and they feed very selectively, especially late in the hatch.
The Green Drakes are on the decline due to environmental degradation.
