Not being a lepidopterist, I have done my best to ascertain the correct titles for these splendid creatures which I have photographed on hikes and travels.  Names in parentheses are best-guesses.  Qualified assistance would be appreciated.

Most images are available for download in 1024×768 JPEG format; a few older ones have a lesser resolution.

Place names are in California unless otherwise specified.
