Weird bug in worms

[poppyseeds]

Hello everyone! I was feeding my bearded dragon earlier and 13 worms in i find a weird bug in my super work container. Ive seen their beetle form before and they are 10 times bigger. Brand new worms from the store. What could it be? (The white stuff is calcium)

Also, can it post as a threat to my beardie?

Looks like Buffalo Beetle (Cleaning crew) breeder use to keep enclosure clean.
