Saw a Monarch and a WTS go at it. The Monarch knocked the WTS from the sky and into a spider web. After the WTS got free he wanted no part of the Monarch and took off with the Monarch in hot pursuit. The Monarch came back and circled the area for about 2 minutes and left. I was under the assumption the 2 would ignore each other. Does this happen often? This is the first time I have seen it.
