Strange large moth type insect
June 27, 2010
Discovered this moth in our backyard in Colorado Springs, Colorado on June 26, 2010. I thought it was a leaf. Very effective camouflage. It was perhaps 2″ long. Can you identify it?

Achemon Sphinx

Dear R. Lee,
Your moth is an Achemon Sphinx and you may read more about this species on Bill Oehlke’s excellent website where he indicates:  “
Those who first published descriptions and assigned scientific names to many insects, simply chose names of biblical or mythological origin without any real descriptive qualities. Their purpose was simply to set a standard for purposes of identification by assigned name. On some occasions, names, mostly of Latin or Greek origin, were chosen to signify a particular character of the genus or of an individual species.  The genus name ‘Eumorpha’ means well-formed.In Greek mythology, Achemon and his brother Basalas were two Cercopes who were constantly arguing. One day they insulted Hercules, who tied them by their feet to his club and marched off with them like a brace of hares.
