I found this question on Y!A

"Hi a few months ago i started raising superworms i tunred them to beetles and had them lay eggs but before they layed eggs ia lso baught mealworms, when the mealworms turned to beetles i placed them and the super worm beetles in the same bucket. (I have all the right stuff and a substrate with everything they need for them and everything my fish need and my turtle need to grow and be healthy and i feed them healty food with water inside like lettuce and apples) the eggs hatched to tiny worms and i had hundreds i wanst sur ethe superowrms had layed eggs but saw them mating so as they grew they looked like plain mealworms but now when i look they are almost grown fully and there is superworms, mealwroms and what appears to be giant mealworms. They are like big mealworms way fatter but have a squished in face, they are not superworms also i can see the difference, could the beetles have bred in the different species and made hybrid worms too."

...Is that possible?

This is the funniest thing... About 30 mins ago I was feeding my mealies, and thought to myself if I could make hybrids with supers haha. I don’t have the answer, but I was literally just thinking of this.

Lol it makes me want to try...but the super beetles are CRAZY scary lol

I highly dout it can happen. A year or so ago, I put a mealworm beetle and a super worm beetle together....The superworm beetle ate the mealworm beetle.

Giant mealworm's are possable with a growth hormone though.

YEAH THEY ARE!! OMG I HATE THEM!!! I really do, I can't stand those, they are just way too big for me!! LOL

What a crazy thing, I would have never put the two diff. beetles together in the same bin though.. you'd think that would cause problems?

I thought so...apparently it just makes mutant mealies lol

I thought this was kind of wierd, one time I tried the same thing, but I put a 5:2 mealworm beetle:superworm beetle ratio, thinking that the mealworm beetles would get eaten. Anyways, I am pretty sure I successfully bred them (the worms were larger than my usual mealworms but smaller than my usual superworms). However, the superworm beetles were the ones getting eaten, the mealie beetles ganged up on them.
