Southwest Monarch Study Sightings

Report monarchs plus their immatures and track milkweed in the Southwest United States. Find and record monarch adults, eggs, larvae and pupae, nectar plants and identify Asclepias (milkweed). Your data will help scientists learn more about monarch breeding, migration density and milkweed habitats in the region. Target locations include Arizona, New Mexico, Utah, Nevada, the deserts of California and Colorado west of the Rockies.
