Dear curious,
We have been getting in increasing number of requests to identify Whitelined Sphinxes, the moth species in your image, and we have decided to make your submission the Bug of the Month for April 2014.  We suspect there might be a significant annual Whitelined Sphinx population this spring, and we also got a Wanted Poster from University of Entomology PhD candidate Cristina Francois to report significant sightings of masses of Whitelined Sphinx Caterpillars.  During favorable years, the Caterpillars, which can be eaten, are found in great numbers.  We are currently observing Whitelined Sphinx Moths very regularly as they are attracted to the porch light.
