Impaction?

I am not sure but I just did a search for "pachnoda" and it looks like it might have a lot of un-digestible shell parts that might be causing some of the problem.

I don't think thats the problem because they are super soft. You must have been looking at the adult beetle form. i feed him the larval stage of them. This is one

I didn't realize you were giving the larva not the adults. LOL
The larva are high fat content so I would feed as treats.
