Posts: 437		Can anyone recommend light and dark Cahill nymph patterns for Western PA. I'm kind of lost on these nymphs. Are they a brownish-olive color? I guess it depends on stream bottom coloration. I know they are part of the same family as the March Brown. Would they be tied in sizes 12 & 14 2x? Any help will be appreciated.

Posts: 2737		There are about a million mayfly species known as light or dark cahills, and there's quite a bit of variety in their nymphs. The more specific you can get about the exact hatches you want to match, the better -- rivers, time of year, size/color of adults, etc. Quite a few people here have enough local PA knowledge they might be able to help you, but just going by PA cahills isn't enough.

HI Lastchance
I fish the same general area your located. I tie mine like a PT with a cream thorax and a dark wing case. 14 or 16 should do it. Sometimes I do well on a emerger, same general pattern with antron (Deer hair) short wing.

They fasten red (crimson red) wool around a hook, and fix onto the wool two feathers which grow under a cock’s wattles, and which in colour are like wax.
