Monarchs are still being observed in the Carolinas, as well as the Virginias. In the Central Flyway, Oklahoma continues to be a hot spot, with movement north toward Kansas and Missouri (latitude 38°N).
The eastern and western monarch populations are divided by the Rocky Mountains. There are two distinct flyways through which eastern monarchs migrate in the spring, the Atlantic and the Central Flyways.
Temperatures are finally warming in the southern range where monarchs are active this week, but Spring is arriving later than in recent years. After a hopeful swell in the overwintering population, monarchs are now in a race to reach the summer breeding grounds before their migration stalls, just a short time away.
