Insects by Common Name
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. Read more...

|Posts: 19||Emergence periods for green drakes usually run for 7-10 days in most streams. However, there are streams in the east where emergence periods are prolonged by some of the nymphs being parasitized by Nanocladius and Epoicocladius midge larvae. In these streams, emergence may be prolonged to 21 days. Unparasitized nymphs emerge before parasitized nymphs, with each group showing separate peaks of emergence about a week apart. This is based upon my own research on green drake emergence in streams with these midge species. |
My question here is this: does anybody know of streams that have this type of prolonged emergence (2-3 weeks) in NY, PA, MD, or WV?

|Yes, the WB of the Delaware in NY has a prolonged emergence period not only for guttalata but for many mayflies. I will see Ep varia on the lower end of the WB by the third week of April and will see them still emerging near the reservoir by May 15 with a spinner fall the next week.|
I often see Green Drakes emerging by my cabin on the lower WB by May 20 - 23 then when the hatch is over on the lower river I will see them in Deposit or the upper East Branch almost to the middle of June.

The Green Drake emerges on all of the major Catskill rivers. The dun emergence seldom last a full week in a specific section of any of the riverss.

|Posts: 19||That fits with what I would expect for a stream that does NOT have these parasitic midges. If they were present, the emergence would last at least 2 weeks, with the first week seeing emergence of unparasitized mayflies, and the remainder being mayflies that had been parasitized.|
Thanks for your comments.

I enjoy the Caucci and Nastasi description of their emergence. I also used it in my dissertation in describing this species. It used to be an exciting time of the year for me for many reasons.
