large pupa Cicada?
This is a picture taken by Missouri Department Of Conservation, we are having trouble IDing this guy. Is it a cicada pupa? Or some type of beetle. Any information you can give will be very helpful. Thank you

Hi Shelly,
This is the pupa of one of the large Saturnid Moths, often called Giant Silk Moths. It can be distinguished from the Sphinx Moth Pupa, also found underground, due to its robust girth and lack of future mouthparts, the Proboscis. Most Saturnid Moths build some type of cocoon, which eliminates many possible species. We are surmising that perhaps this is a Regal Moth, but your best course of action is to wait for the adult to emerge.
