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