a monarch chrysalis hangs from a common milkweed leaf

 Image Number d4226-1

A monarch chrysalis hangs from the leaf of common milkweed, Asclepias syriaca. This is the stage in the life cycle where the caterpillar changes to a butterfly. According to an ARS and Iowa State University study of nine milkweed species native to Iowa, female monarch butterflies laid eggs in all nine milkweeds, but the swamp and common milkweed averaged the highest number of eggs.
