Fly Fishing During Caddis Fly Activity
July here in Montana means heavy hatches of caddis flies. But seeing lots of caddis in the air does not mean they are necessarily emerging. This time of year it’s common to see flights, or balls of caddis,around bushes and trees. This type of activity is actually a mating swarm. Mating swarms usually occurr in the late afternoon and evenings. Don’t be confused by the huge numbers of caddis and lack of rising fish. If you look closely, you’ll notice the flies are not actually on the water. But stand by! Generally speaking the insects you see swarming in the bushes will begin ovipositing eggs and will hit the water and eventually die, creating a great spent caddis feeding frenzy. If you’re in the right place at the right time, you’re in for some great dry fly action.
