Sorry but I have to disagree. There are indigestible parts. Hornworms are much larger but their is never undigested parts. The reason being that they are softer so everything is digestible. Don't get me wrong, roaches are a good feeder and I kept them for a couple years. This is the first season that I decided to not feed them at all. My primary food is Silkworms. I also keep crickets, superworms, and hornworms.
