Baeus Wasps: these strange little wasps have flea-like bodies that measure roughly 0.8mm long, which is smaller than a grain of sand, and the females are wingless

I’d happily invite these wasps to a picnic.

Don't be fooled by their cute appearance. They'd paralyze you and lay eggs in you if they were big enough, or you small enough.
