We have our first radio-tagged monarch detected in Oklahoma this spring!
ROS032 was detected in Oklahoma yesterday, March 25. In addition to being the first radio-tagged monarch detected in Oklahoma this spring, he's also the farthest north of the radio-tagged monarchs.
As we continue to follow along with the radio-tagged monarchs through the Project Monarch Science app (available to download for free via your mobile device's app store), don't forget to submit your first sightings of monarchs and milkweeds in your area to Journey North! Every sighting you share - whether sightings of monarch butterflies, eggs, larvae, or even milkweed plants - contributes to understanding monarch migration dynamics.
