Heres some clarification. Mealworms can be kept in the fridge with no adverse affects, and should only be fed to you chameleon a few times a month because they are very chitinous. Superworms, look like mealworms, but should not be refridgerated as it kills them. Superworms make good staples (along with crickets or silkworms, etc) as long as you gutload them well.
