Nymphs that resemble a number of different kinds of insect larvae and nymphs are probably the most practical. Such old standbys as the Muskrat Nymph and the Hare's Ear are well worth carrying, as are imitations of large stoneflies and dragonfly nymphs.

Attractors such as the Woolly Worm and its cousin the Woolly Bugger, Green Weenie and the [censored] Creek Nymph. These resemble a variety of aquatic critters.

A bugger resembles nothing in nature when it's perched in a vise, but when it is soaking wet and on the move, it truly comes alive. Depending on hook size and how it's weighted and retrieved, it can mimic a minnow, crayfish, leech or aquatic insect.

The Weenie, besides a flash of color, can mimic a catapillar or inchworm.

Every stream sampled usually contains at least a few green-bodied caddis, and in many rivers they are a trout's daily special.

The Green Rock Worm patterns actually represent a couple of so-called "free-living" caddis species. These larvae don't build portable houses for themselves but instead crawl among rocky crevices and clumps of vegetation on stream bottoms.

Dry flies such as Blue-Winged Olive in small size hooks ( 12-18 ) may be worth the while. They usually are a staple spring mayfly hatch and in the west sometimes in Winter.

Caddis hatch at sporadic times during the winter months on many waters, so it makes sense to carry a few Elk Hair Caddis, or something close to it.

Also, cold weather or winter plays well for what are called Streamers. Lethargic trout are less apt to go after nymphes (larvae) but being cannibalistic are more prone to strike small fish or crayfish which a streamer may represent.

Note: Dry flies are cast upstream and allowed to float downstream, while Wet Flies and/or Nymphes (larvae) are cast across or downstream with a small split-shot weight and drawn against the current for a swimming action.

The Green Weenie was developed by Ken Igo and Russ Mowry of Westmoreland County, Pennsylvania and introduced to South Central PA and the popularity of this simple fly has spread rapidly throughout the country. Probably, this is due in no small part to Charlie Meck’s book Pennsylvania Trout Streams and Their Hatches, in which he talks about first using it while fishing with Russ Mowry in Western PA.

As the fly is very effective on brown trout, though other trout will hit it, Fred figured something red would work even better for rainbows and brook trout. Tied with fluorescent fire orange chenille, the Red Hot is to rainbows and brooks what the Weenie is to browns.

By the way, tied on #6 or #8 long shank salmon hooks, both flies will take salmon from the upstate NY rivers.

Fished unweighted and allowed to drift on the surface, it can represent a small catapillar or inchworm.

I DO have to wonder where they come up with some of these names, though...Green Weenie indeed! And Wooly Booger? Nope, not gonna go there ...

well they also call it the wooly bugger and its cousin the wooly worm .... which is a bugger without the tail ... maybe with a bead head. Now this definitely is not to be confused with the green weenie, unless of course you have a red or flaming weenie ... kind of a glowing red weenie.
