Is there only one species in the state or only one that looks like this?

That's why I moved a buch of nymphs for some regions, but not for others. I'm sure they probably can be told apart, but the problem is learning which is which. Assuming there is nothing else that looks the same as S. furcata/mexicanus, I can probably identify them from anywhere now, but I'm not confident that there aren't one or two more that look the same, so I probably won't move any from where there are multiple species in the same area. There are a few more regions with only one species that I haven't sorted through yet, but I'll try to get to those too, and maybe learn some more. Too bad there (apparently) are no references to identifying Katydid nymphs. We may be building one here, but it will be slow going - trying to connect the nymphs with the adults.

but had little luck. They are fine for a while, but then something goes wrong. I assume I'm not doing too well with their diet. They start eating what I give them, so I feel confident, then one day...
