Yesterday afternoon, May 20, we were out looking for milkweed in a prairie area west of Slater, Iowa, on the north side of the Heart of Iowa Trail. We found numerous sprouts from 2 to 5 inches high, and on seven of these, we found a single Monarch egg on each.

I haven’t seen any Monarchs yet, but at some time within the last several days, they’ve passed through our area and deposited eggs.

The temperature yesterday was 56 F, under 90% low cloudiness and wind from the northeast at 12 miles per hour. Weather was not favorable for Monarch activity then or on the day before that. I think that the Monarchs might have arrived and laid their eggs sometime on Saturday, May 18, when it was 80 F and warm, moist winds were blowing from the southwest, several hours ahead of a rainstorm, after which a cold front passed through from the west.

Editor's Note: The presence of eggs means an adult monarch has arrived in this area. Therefore, we are adding this egg report to the migration map.
