Check out Joshua Williams’ take on a Zebra Midge, and easy but extremely effective pattern for nymph fishing.
The Zebra Midge is a great fly to use as a dropper, especially in tailwaters. Midges hatch year round, making them one of the few species that can be used in the winter as well. The most common sizes to be equiped with should be in the #18-24 range in any color that works well. Great additions I include are always using an Ice Dub collar and applying Clear Cure Goo for added shine and durability.
