Maybe... there is no photo of the caterpillar (and I can't take one now, lighting too bad). They are bright green but I don't see any diamond shape on their back.

I thought I would keep them, but then I realized that they need to stuff themselves with enough food to last the winter. They would just eat through all my salad, then starve to death. So I will release them into the "wild" this week-end.
