This past week I was fishing a high mountain lake and encountered the oddest bug I have ever seen, or encountered in 60 years of dry fly fishing. It was 1" long, with long, semi clear wings. It had a thin, olive body, with black ribbing like a bee. No tail.
The odd thing was that it had a long, thin, black neck, almost 1/4" long, with a big black head.

Fortunately, I was able to modify an extended body, olive mayfly, almost as large as a callibaetis, and clip the tail, and make it work.
Once I clipped the tail the rainbows ate it eagerly.

After doing a search, I determined that the bug was a "Snakefly". I will certainly have a few of these tied up, for my next trip!

I would be curious to find out if others of you have encountered this "monster" bug.

Note: When I plucked the bug from the water, grabbing it by the wings, it actually turned its head and tried to bite me. No joke.

That's my story, strange as it may be.

Cheers,
