It’ s Trico time on many trout rivers and streams, especially here in New Mexico. Tricos adults have three tails with a small, black body and clear-to-whitish wings similar to scotch tape. Tricos are small to tiny mayflies, ranging from size 18 down to 22 or even smaller. In New Mexico, we have an early Trico hatch that is size 16, but for the most part we see sizes 18 to 22. Here are several highly effective Trico patterns for fishing fast riffles to slow moving water.
