Large numbers of monarchs moving through from Sept. 17 through Sept. 21. Peak of migration normally occurs about 2 weeks earlier for this latitude. Monarchs were feeding heavily on New England Aster and Prairie Dock.

The largest numbers were between Sept. 16 and 19. At any one time I would guess there were 12-15 monarchs in a garden of about 500 square feet. It doesn't sound like a lot, but it's more than I saw during early September, which is supposed to be the peak time for our latitude. Butterflies were so focused on feeding that I was able to catch them by hand in order to tag them - no net required!
