I adhere to the belief that when we see a "heavy hatch" of caddis flies, we are probably witnessing swarming males above the water and female egg-laying caddis diving to the water to release the eggs from their egg sacks - sort of a reverse hatch! Most of the females swim down to the bottom to release their eggs there. Trout key on these females and their egg sacks.
Gary LaFontaine reviewed this situation in his book: Caddisflies
