Well, I put 2 supers in a small container and put that in the fridge (not freezer) to check that the supers I got are really supers and not those hormone mealies; I thawed it after 24 hours, only one was dead, the other one still moves a bit. Could they be supers? How long do you need to fridge them to do the superworm testing?
These supers are from my own colony, the beetles are large. If I happen to have king mealworms, will their colony be the same too? will their baby worm grow to the same size as supers too?
) but supers are a lot bigger than the steroid-fed king mealies. Supers also have a greyish-brown black color, while king mealies have the same yellowey amber coloration of a normal mealworm. They are both completely different beetle species. And, last i knew, the whole reason why the big mealworms are so big is because they are fed a steriod to make them bigger, and it also prevents them from pupating (sp?) so they cant turn into beetles. If they turned into a large bettle i would say you have superworms. hope this helps!
