Help! What are these? Should I throw these dubias out?

Bought 1000 Dubia Roaches at this weekends reptile expo and when I put them in their new holding area, I found these weird worm like things! Are these bad? Can anyone identify them? Should I get rid of these dubias?

They look like meal worms or little super worms from here.

Some sort of darkling beetle larvae. People use them as cleaner crew for many roaches. Probably a million threads just like this out there lol, harmless.

I thought that too but then I also found some of these black beetles… I wonder if these worms turn into these?

I looked at some of the threads but a lot of them had the black, fuzzy ones. They don’t seem to be bothering the Dubia’s so as long as they are just cleaning, I guess I’ll leave some of them in

Mealworms and superworms both turn into beetles. Those are lesser darkling beetles you're seeing.

Those are buffalo beetles (Alphitobius diaperinus), also known as lesser mealworms, a species of darkling beetle like @jamest0o0 said.

They're interesting in that the larvae/worms get bigger than the beetles they pupate into... Helpful clean up crew, but can get a little overpopulated at times. I like to trap extras in my guns by leaving a 1" deep plastic dish with a bit of cat food (they love protein) in the bin. The roaches are big enough to get out (besides the occasional baby), but the beetles are stuck. They make a nice crunchy treat!
