This page is inspired by and dedicated to Laura Pound who provides the Arctonotus lucidus image above, as well as additional images via link below thumbnail image.
Laura writes, "I took these photos of this beautiful green moth last night, and I found this site while attempting to identify him. He was in the garage, on a damp towel I needed to launder, so I coaxed him onto my hand and took some photos."
Laura originally submitted some of the images to "What's That Bug" for identification, and Daniel Marlos notified me of the sighting.
Thirty-two Sphingidae species are listed on the BAMONA website for California. Not all of the species are reported by BAMONA for Mariposa County. (Ten species: Manduca quinquemaculatus, Paonias myops, Smerinthus cerisyi, Sphinx perelegans, Sphinx sequoiae, Arctonotus lucidus, Eumorpha achemon, Hemaris thetis, Hyles lineata, and Proserpinus clarkiae are listed by BAMONA for Mariposa County.)
It is hoped that this checklist, with the thumbnails and notes, will help you quickly identify the moths you have encountered.
A WO" after the species name indicates that I have no confirmed reports of this species in your county, but I (William Oehlke) expect that this moth is present.
A green BAMONA indicates the moth is reported on the BAMONA website and/or in Moths of Western North America, #2. Distribution of Sphingidae of Western North America, revised, an excellent little booklet available through Paul Opler.
Please help me develop this list with improved, documented accuracy by sending sightings (species, date, location), preferably with an image, via email to Bill Oehlke.
Please also forward sightings to BAMONA, an excellent online resource.
Many thanks to Tarah Eastwood who provides this nice image of what I believe is a Smerinthus ophthalmica male.

Macroglossinae subfamily

Fight would be from June to August. Larvae feed on grape foliage.

Proserpinus clarkiae BAMONA, Clark's Sphinx: The upperside of the forewing is greenish gray; the median area may be dark or pale. The upperside of the hindwing is bright orangish yellow with black borders.
