Blue-winged Olives
Baetis

Tiny Baetis mayflies are perhaps the most commonly encountered and imitated by anglers on all American trout streams due to their great abundance, widespread distribution, and trout-friendly emergence habits.

The "Fountain Flats" stretch of the Firehole was fishable in the morning after an uncharacteristically cold August night.

This dun emerged from a mature nymph on my desk. Unfortunately its wings didn't perfectly dry out.

27" brown trout, my largest ever. It was the sub-dominant fish in its pool. After this, I hooked the bigger one, but I couldn't land it.

Several anglers fish the tail of a famous pool, loomed over by a Catskill mountain.

Here's a start, Jesse:

Slate Drakes (Isonychia bicolor)
Little Sulphurs/PEDs (Ephemerella d. dorothea)
Summer Blue Quills (Paraleptophlebia spp.)
Light Cahills/Salmon Spinners (Maccaffertium and Stenacron spp.)
Yellow Quills/Pink Ladies (Epeorus vitreus)
Little Yellow Quills (Leucrocuta spp.)
Golden Drakes (Anthopotamus spp.)
Little BWOs (baetids)
Golden Stones (Acroneuria and Paragnetina spp.)
Spotted Sedges (Hydropsyche spp.)
Little Sister Sedges (Cheumatopsyche spp.)
Long-Horned Sedges (leptocerids)

...or you could just throw streamers.

What Gonzo said but if you hit high water and have a boat bang the banks with streamers and hold on! I'm always partial to white streamers in lower light for big browns and the Delaware is full of those. If you dont have a boat then it is difficult to cover enough water to reall make the streamers pay.
The Delaware also has potential for almost blanket Isonychia (aka slate drake, white gloved howdy) hatches probably the most intense late summer iso emergence I ever encountered happened on the Mainstem.
