I raise stray katydids that show up on our herbs every year- last time, a male whose life cycle I posted turned out to be S. fasciata. Both species are known in my backyard. Over the course of the four years I've done this, I have learned that they prefer basil (leaves and flowers) as food, while also accepting spinach and petunia flowers. Just this year, I made a point of discovering which wild species they eat; so far they have accepted lambsquarters and red sorrel (but only when basil is unavailable), as well as their own shed exoskeletons. I'm behind on posting photos so these are a few years old- right now I have two, one is a third instar female and the other a second instar whose gender I haven't been able to determine yet.
I also raised a female with this male, photos of the adult are here. Hopefully this can help with the ID, if they are in fact the same species.
