The inside of this cocoon is as smooth as satin and the larva after changing to the proper state is glossy black, from one and a half inches to two inches in length. As the time draws near for the great change to the beautiful moth, the pupa grows very soft and, moistening the smaller end of the cocoon with a secretion prepared for this use, comes forth with damp, small wings, which as they dry out develop into the regular size of the beautiful moth, leaving a round hole in the cocoon where both the outer and inner cocoon were woven less closely and strong than any other portion.
In New England the cecropia may be found in the month of June.
Often the larva uses a leaf in forming the outside, and after a leaf dies and is blown away the impress of the veins remains, making such a pretty cocoon. You can easily find them during the winter months, when the trees are bare, if you keep a sharp watch for them.
