What is this? Larvae?

[Diplopodia]

I purchased some millipedes and to my surprise they were delivered with a handful of isopods and this creature in the mix.
I assume it's the larvae of an insect but I have no idea what it could be.

Looks like either a mealworm or a young kingworm

It's likely either of what WhiteMoss suggested. Careful with the isopods since they've got a reputation for gnawing on molting inverts.

Thanks, after looking it up I agree. Yeah I know. I had to go through and separate them all. I wasn't too happy finding isopods with the millipedes especially since it was a shipment of juveniles less than an inch long.

I would watch out for more if they were mixed in with your millipedes. If hungry mealworm and kingworms will even cannibalize their own so they'd very like devour you molting millipedes.

Thanks. I'll definitely keep an eye out for any unwanted creatures. I tried my best to remove them from the substrate they came with.
I put the isopods in there own enclosure and put the worm by itself with a springtail loaded substrate.

Sounds like a very unorganized vendor.
