CADDIS FLIES

A very important fly, especially in the West. On many rivers it is probably more important than the mayfly. The Provo River has some very large Caddis hatches. These usually occur from the middle of the summer until September and into October.

Unlike the May fly which hatches from a nymph, the caddis fly hatches from a larvae. The caddis worm builds a small case for itself to protect it from things like fish, but this case does a poor job. Locally these larvae are called "rock rollers."

The species of caddis most prevalent in the Provo River is a medium brown type, but other caddis flies are present that range in color from dark brown to apple green. Their cases range from the common cone-shaped type formed of tiny pebbles to those which have cases formed of small sticks and those which are square.

Suggested Fly Patterns:

Larvae: Caddis worm, Potts Sandy Mite, Lady Mite, Hare's ear, etc.
Adult: Little Caddis, Bivisible, etc.

NOTES:

When imitating the caddis fly, always catch a specimine, for if you try to match them by simply watching them fly you may find your immitation is too light or dark.
