RE: Saw a scary thing...well just sort of disgusting
just a parisite , only in hot weather.when I was a kid ,they called them wolves.
I always heard if you see a cow running with it's tail held out stright or up high , it was trying to get away from the fly.the fly lays an egg in a small wound and the wolf starts to grow till grown and falls out to become another fly and the cycle starts all over again.
nature has many wonders.
