The monarch abundance peak for our latitude (41° N) according to monarchwatch.org is September 8 – 20. Perhaps the mild weather in late September and early October convinced these four monarchs to stay longer. Wednesday, October 3, when I took this photo, the high temperature was 70° F. Today, the forecast high is 57° F.
I hope these late traveling monarchs have journeyed far enough south in 5 days to avoid the cold front. The one day travel distance record for a monarch is 265 miles. This means that these four might already be 1,325 miles away. As a point of reference, Atlanta, Georgia is a little more than 1,000 miles away from Hartford, Connecticut.

Fun fact: Monarchs east of the Mississippi migrate to forests in the mountains of Mexico, while monarchs west of the Mississippi migrate to forests along the California coast.
