Red admirals are among the few species of butterflies that have a two-way migration. In Iowa this year we had huge numbers of this butterfly early in the summer, then their numbers went way down.
Friday I saw six in about 40 minutes. All were flying fairly rapidly, and all were going in about the same direction–south-west along a hill. The flight of red admirals is a little more dispersed than that of monarchs, so their migrations are not so noticible.
We probably won’t see them in large numbers again until next year.
