Posts: 1I was fly fishing a tailwater in Indiana when I noticed a {hatch} of what I thought were sulfers(dorothea,invaria). But after further inspection they had the makup of a crane fly and also were a pale yellowish color. Could this be a crane fly species?

Definitely. Small pale yellow craneflies are especially common on trout streams. I don't know any more about those species, but I'm sure trout go for them at times.

Yes, Flyfisher's Paradise in State College even has its own patterns for orange and yellow craneflies, and I've had very good luck with the flies in autumn.

Cranefly larvae are often really huge, and probably a juicy treat for a hungry fish. What kinds of patterns mimic these, and how commonly are they used?

Probably, the vast majority of flyfishers have never specifically set about to imitate crane fly larvae. However, 3-4XL hooks utilizing a dubbed body of muskrat fur would be standard fare for such imitation.

Two patterns suggested in Western Hatches by Hafele/Hughes are Polly Roseborough's Muskrat, and Ernest Schwiebert's Western Crane Fly Larva. The imitations are said to be most effective fished tumbling along the bottom, shortly following a spate, which has disturbed their larval habitat.

Another good crane fly larval imitation is the Walt's Worm. The larval crane fly imitations I've seen are basically really vaguely buggy, cigar-shaped imitations that work for both caddis and crane fly larva. Perhaps it's not a lucrative enough hatch to try to imitate them specifically (or they may just be similar enough to caddisflies that most fisherman simply imitate both with the same larval imitation), but I can recall days her in Central PA when crane flies were the only things flying around.

I agree with Taxon, the vast majority of tiers do not imitate a crane fly larva, but they should. In the waters that I consider my backyard (Golden Trout Wilderness, Sequoia NF, CA) a crane fly larva is a mandatory summer pattern for the meadow sections of streams. One of the local species is the Giant Western Crane fly (Holorusia rubiginosa). A proper imitation of a mature larva may go up to 50mm by mid-summer, which I have used only in the largest of the surrounding streams, but then it has accounted for rainbows over 22”. Most often we use smaller patterns. One I can recommend, to be added to the pattern listed by Shawn, can be found at Charlie Craven’s website, under Crane fly larva, it's the one I use:

If you are unsure of the size, stay small.
