Migrating Monarch Butterflies Detectable On Weather Radar



Observers of radar data noticed some large blue blobs on weather radar last week moving over southern Illinois and central Missouri. According to the U.S. National Weather Service in St. Louis Missouri these were likely swarms of monarch butterflies, headed to their winter home in Mexico. These tough little insects have survived a tough season after an unusually cold winter, ongoing drought, and a lack of milkweed.
