Dr. Taylor trained as an insect ecologist. He has published papers on species assemblages, hybridization, reproductive biology, population dynamics and plant demographics and pollination. Starting in 1974, Taylor established research sites and directed students studying Neotropical African honey bees (killer bees) in French Guiana, Venezuela, and Mexico. In 1992, he founded Monarch Watch, an outreach program focused on education, research and conservation relative to monarch butterflies. Through the last 20 years Monarch Watch has enlisted the help of volunteers to tag monarchs during the fall migration.
