Another view appears in the illustration below of a moth,Stenoma schlaegeri, which I found in the woods.^ The circum-stances under which this moth was found show how persistentlycertain sluggish behavior is associated with color markingsand form. When I came through the woods, this moth was. The Moth Stenoma schlaegeri on the upper surface of a straw-berry leaf.

The wind was blowing quite strongly at the time,which caused the leaf on which the moth was resting to swayback and forth, yet the moth held fast to its position. In the sketch of the Animated Rolled Leaf will be foundobservations on similar habits of Datattia moths, of openlyexposing themselves on the surfaces of leaves. The resemblanceof this moth to bird excrement was so close that when firstnoticed I almost decided to pass it by.
