This species here is a real stunner amongst the Sphinx moths (Sphingidae). In America, it is largely restricted to the Southern 1/2 of Florida and the Eastern 1/2 of Texas (along with some spotty occurances along the Gulf coast states between). In life, these moths are of a "deep green" color overall; blending in perfectly with the foliage they rest upon during the day. There are only 5 or 6 records of it appearing as a "stray" anywhere else in America. Two other recorded strays hail from Canada. It is most likely that all of the recorded strays were carried by the high winds aloft via large storms (hurricanes) slamming into the Gulf coast and "petering out" northward.
My only specimen was self caught by me in the Dominican Republic in 1990. It was deep green when I first had it but, over the years it's green color has become more yellow-green with age. Its still a great species overall and it has some of the longest delicate "thin" legs on a hawkmoth I've ever seen.
