Hello,
It is pretty easy to start insect colonies, though a little time consuming depending on what you are trying
to keep.
The superworms are good feeders, as long as he gets a balanced diet & eats his greens & vegetation. I
have fed superworms for years. I just feed less of them than I would if I were feeding crickets only, or silk
worms, etc.
I would keep superworms as a feeders. You can use the dubias, maybe some silkworms or hornworms.
If you want to start your own silkworm colony, mulberryfarms.com has just got in silkworm eggs. They
are in the process of relocating to another state but they do have them at the moment. So you could start
your own colony of those if you wanted.
You could check out Rodentpro.com they have a variety of insects, too.
