We know by the wet moth that liquid is ejected, although
we cannot see the wet spot on the top of the inner case of Cecropia
as we can with Polyphemus, that does not spin the loose outer case
and silk nest. From here on the moths emerge according to species.
Some work with their mouths and fore feet. Some have rough
projections on the top of the head, and others little sawlike
arrangements at the bases of the wings. In whatever manner they
free themselves, all of them are wet when they leave their quarters.
Sometimes the gathered silk ends comb sufficient down from an
emerging Cecropia to leave a terra cotta rim around the opening
from which it came; but I never saw one lose enough at this time
to disfigure it. On very rare occasions a deformed moth appears.
I had a Cecropia with one wing no larger than my thumb nail, and
it never developed. This is caused by the moth sustaining an injury
to the wing in emergence. If the membrane is slightly punctured
the liquid forced into the wing for its development escapes and
there is no enlargement.
