wife-keeper, candle-peeper, one of sisters three. large and low is how I grow do you know me?

I am a hunter with fangs and usually hair. Some people come close only as a dare. I have legs but I don't walk on four. I like my home off the floor. I hunt with line and play with my food. Please don't hurt me, I really do good.

In moonlit skies, I take to flight, A shadowy form, with wings so bright. I feed on blood, with a special flair, My prey sleeps tight, without a care.

I have a security job, but I do not have a break. I am often seen in farming fields.

I am here, then I am not, my place of birth is often quite hot. To my origin, you are no stranger, to you it may prove as salvation or danger. Even if you get caught in my snare, you do not for long, as I dissolve in thin air.
