Personally, I would not feed anything that I did not raise myself, or buy from a reputably breeder. That moth might just have stopped at my house before you caught it and might just be full of pesticide (or even parasites).
Mirage came out of brumation on April 26. He was doing great. On May 2 he started acting funny. We just redid his tank, and he keeps going into one of his hides. He just lays there. He shows no intrest in food. HELP!
