I like this article in Nature Canada celebrating Canada’s (and North America’s) largest moth, the Cecropia moth. It is an excellent moth.
“Adult Cecropia moths last about two weeks. They can’t eat during this stage, since they have no digestive system or moveable mouth parts. About the only thing they can do is mate! An adult Cecropia moth is basically a work of art designed to create more works of art.”
