This time of year if you open up a Grannom case, it will probably either be empty, because it already hatched, or it will contain a pupae.

I could be wrong, but I think it's very unlikely that you would find a larva in the case, because they've already changed into pupae, getting ready to emerge.

That doesn't mean the fly wouldn't catch fish now, of course. All flies will catch some fish. But if you really want to imitate the naturals the trout will be seeing, you might tie pupae patterns instead.

Most cased caddis pupate within their case. When ready to emerge, they cut through it with their mandibles and swim or drift to the surface and emerge as adults. The pupae do not live outside their cases for any length of time. If you find empty cases, the caddis have already emerged.
