Was excited to try a new-to-me spot just outside the town of Greenwood, SC today and find my beloved ol' Christmas Darters. What was interesting was that of the two I caught, both gravid females, was how un-hopkinsi they looked. I've noticed slight differences in patterns between E. hopkinsis across their SC range. Some are much prettier than others. I've also noticed many females "darken up" when gravid, but have never seen any this different from "normal" coloration. Thank goodness for the band in the first caudal fin!

Did you notice any difference in habitat/substrate as compared to other sites you normally sample?

Not really, Michael. Though this spot had a few more car parts than most...

Catalytic converter, cut off and dumped over the bridge, natch. Actually, the spot was surprising clean for its location. Other than this, two batteries (car and motorcycle), and a vicious looking rusty stake (apparently for stabbing steel vampires) this spot was very clean.

Stuck to the right of way at the bridge, so didn't have a chance to check out too much. Didn't catch many fish, but the ones I did catch were big and healthy. Mostly females, too. Here's two more pics I didn't have time to post this AM. I still don't have a decent theory for the variations in color. But I suppose variation in darter coloration isn't exactly unprecedented...

I know where the stripes are supposed to be on this gal and it's still all I can do to see 'em.
I don't think I've ever seen such diagonally oriented saddles, either, but I suppose I could have just overlooked it before.

Since we're talking variability, here's the Notropis lutipinnis that were taken here.

I don't know what that cray is. I think we id'ed it in the crustacean subforum a while back. Pretty common whatever it is.
