Lunesta (eszopiclone) butterfly: Lunesta, (eszopiclone) a sedative/hypnotic used for insomnia has a green "butterfly" or moth in its advertising. It can cause dependency, and affect motor performance, memory and cause confusion, especially in older people, as all in this class usually do. If this is not the butterfly you mean, ask again.
