3.   Cinnamon Caddis - Mostly Abrams Creek
4    Light Cahills - hatching
5.   Midges - hatching in isolated locations
6.   Little Short-horned Sedges - should hatch randomly for 2-3 months
7.   American March Browns - hatching but randomly in isolated locations
8.   Streamers - matching sculpin, baitfish and small crawfish
9.   Little Yellow Stoneflies - hatching
10. Green Sedges - hatching
11. Little Sister Caddisflies - Mostly Abrams Creek
12. Eastern Pale Evening Duns - (called Sulfurs by some)

16. Slate Drakes - hatching

Slate Drakes - Spinners:

The spinner fall is the best and really only part of the hatch that you can fish. They
would rank second to the nymphs but can provide a lot faster action if the timing is
right. To refresh your memory, remember that the nymphs crawl or climb out of the
water on the bank or objects that protrude out of the water such as rocks to emerge.

Like other species that hatch out of the water, trout do not have an opportunity
to eat the duns, unless they accidentally get into the water. You have probably
noticed fly companies that sell flies for the Slate Drake Dun. If they do, it is either
because they just want to sell something or they just don't have any idea of what
they are trying to imitate.

Slate Drake spinners are commonly called "White Gloved Howdys" because
they look like they are wearing white gloves on their front legs. The spinners
usually come back to the stream within two days of hatching out. Mating takes
place on shore and then the female deposits their eggs by hovering over the
surface and dipping slightly into the water. This activity usually occurs very
late in the day or after dark. Theres usually not a substantial number of
spinners on the water at any one given time and the activity that occurs depends
largely on other food that is available at the time. If most other aquatic insects have
hatched, the Slate Drake spinner fall can be a very important thing to fish. It doesn't
take many of the large flies to get the trout's attention and it all happens within less
than an hour.

Spinner Presentation:
If you see females depositing their eggs on the surface, then you should
fish our "Perfect Fly" Slate Drake Spinner.  These mayflies usually fall spent in the
same water they hatch from. The riffles and runs provide most of the action but the
spinners end up congregated in the eddies, heads of pools and pockets along the
banks out of the fast water. The trout don't need to eat them in the fast water. They
know they cannot escape and they usually just sip them in the slower water below
or downstream of the runs and riffles. The ends of long runs and riffles and the
heads of pools tend to collect most of the spinners. If it is during the hot summer or
early fall, you may even want to try the spinner imitation early in the mornings.

This is our "Perfect Fly" Slate Drake Spinner
