yeah, they can look very similar but there are dead giveaway features that distinguish the two from one another. You can go to just about any woodland waterway in norther CA or parts of Oregon and catch elegans and atratus too. Very large, feisty ones I might ad. Aside from their plain coloration, they're one of my favorites.

I really like this zaxanthus (used to be classifed as a ssp of atratus)
