Los Angeles County, California

This page is dedicated to Clark Thompson who has provided me with images and data for Catocala and Sphingidae species from California. Clark is also the moderator of Insectnet.com.

Many thanks to Dan Yokich who has sent me images of Smerinthus cerisyi from Los Angeles on April 14 and April 27.

Thirty-two Sphingidae species are listed in the USGS for California. Not all of the species are reported by USGS or anticipated in Los Angeles 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 Los Angeles County, but I (William Oehlke) expect that this moth is present.

A USGS (now BAMONA) indicates the moth is reported on the USGS 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 send your sightings to BAMONA, an excellent on-line resource.

Many thanks also to Tim Bonebrake who sends the following image from Hollywood:
