Bloodworm?

I keep seeing something called bloodworm when I'm looking for dried insects. Does anyone know if these are ok for hoggies? It says they're 58% protein and only 6.5% fat so that aspect seems pretty good. Any ideas?

The only type of bloodworm i can think of is the stuff you would feed to fish, not sure i would recommend it for hogs though.
If you buy live it comes in water and you risk contaminates as its actually mosquito larvae, if you buy it frozen and defrost it, it becomes soggy and the freeze dried is powdery and i've never known a fish to eat it let alone a hog
Plus i know for def with fish once you start feeding this, it becomes highly addictive

Hoping now that there isn't some other form of bloodworm, as i'm gonna look an idiot
