History

Gilbert Rowley started tying the Mayday Mayfly right out of college around 2010. The tinsel underbody on the abdomen was inspired by Lance Egan's Rainbow Warrior — this was before Lance and Gilbert had become friends, and Egan flies were already staples in Rowley's box. After some trial and error, he landed on a few variations that fished consistently well. The hot-orange wire rib serves as both segmentation and an attractor, and the Simi Seal dubbing adds a super-buggy element to the thorax. Fast to tie, reliable on the water — a searching-nymph go-to.

Fishing tips

Fl. orange rib is the trigger. Don't overdress the Simi Seal — a tight, compact thorax works best.
