Name: Michele Roth N.E. Indiana - Zone 5b, and F (Zone 9b) I'm always on my way out the door..
Could be ants...could be the drastic change in conditions, too, especially from super wet to hot. They might have started to blight or rot during the wet and are showing it now due to the stress of the heat. Part-shade, I'd say, and cautious watering. No fertilizer for a while, either.
