Abstract

Monarch butterflies, Danaus plexippus, yearly roost by the thousands in certain trees during their southward autumn migration. A study of a roosting tree in Manning, Iowa, suggests that monarchs originally chose the tree for the characteristics of its maple leaves and its physical location and proximity to nectar-producing flowers. It is thought that later generations of monarchs were drawn to the tree by a combination of a residual sex attractant odor and favorable wind conditions.
