Post frosty morning

While watering the plants this AM, temperature was in 50's, I noticed that the salvias suffered frost "burn".  It had to be the frost that I took pictures of the previous morning. There was no frost on plants.

The Country Girl mums don't seem to have any burn.  They are not pretty (photographer wise, but still a joy).

While I was out watering this morning, I spotted a black butterfly. I have no idea what it was. The odd thing about it was it had something attached to the lower wings. When I disturbed it, it flew and the wing had some sort of bug attached. I have no idea if it was a spider or what.  This is a good time for a SLR camera. What ever it was was not normal.
