Dried Silkworm Pupae are a 100% natural, high quality, high protein nutritional crunchy treat which can be fed to many animals including wild birds, hedgehogs, turtles, Koi and other fish and many reptiles. As well as being naturally high in protein they also have high levels of calcium, nutrients, vitamins and minerals and other essential fatty acids. We can't pretend that they aren't a little bit stinky though!
