Unexpected hitchhiker in feeder cricket tub?

[Flammendehaar]

I've had a tub of feeder crickets for my assassin bugs for well over a week now, and there are not so many crickets left in it any more (once those bugs start to eat, boy do they eat!).

I just did a feeding and tipped a few more in for the bugs, and when I was taking a look to see how many were left in there, I noticed something moving strangely in the tub.

I took a closer look and to my surprise spotted this big hairy grub thing:
Does anyone have any clue what this critter is?

Thanks!

I always get rid of them

They are determnid beetle larvae ( not sure if correct spelling) they eat the dead crickets and stuff, basically cleaners, I wonder though if I can keep the adult with a forest Scorpion

Dermestid beetle larvae

Though I do wonder this because you can keep blue death feigning beetles with desert hairy scorpions so I was naturally wondering if there was a tropical equivalent

Dermestid beetles like it dry too. For a forest scorpion, just use springtails and dwarf white isopods as clean up crew.
