Ahh spring, Montana really comes alive during the spring months with the arrival of warmer weather. After a long winter fly anglers are chomping at the bit for more pleasant weather and events like the Mother’s Day caddis hatch.
Timing the Hatch
Mid May is when we see our first caddis emergence. This really depends on weather and water temperatures. These bugs start to hatch when water temps hit the 50’s. As the weather warms up, the caddisfly larvae become more active and start to pupate. During this stage, the larvae undergo a transformation and develop into winged adults. When the pupation is complete, the adult caddisflies break out of their cases and emerge through the water column and break the water’s surface film.
Mother’s Day Caddis = Happy Trout
The emergence of the caddisflies can really have hungry trout looking up. The caddis mate in mid-air, and the females return to the water’s surface to lay their eggs. During this time, the adult caddisflies are vulnerable to predation as the bounce and skitter on the water. Trout take advantage often gorging themselves on these protein packed insects.
Prime Time for big Dry Flies
Fly fishing the Mother’s Day caddis hatch is a prime time to fly fish for trout with dry flies. We see the best hatches later in the day. Fishing high floating dry flies makes for some exhilarating strikes. Below are tips for Fishing the Mother’s Day Caddis Hatch in Montana.
