This plant is on my lake shore in Cass County. I used to have lots of black-eyed Susans, but this year they look like something has infested them (or replaced them??).

I believe your plant is a heliopsis helianthoides, common name oxeye. For more information, check the following sites:

The insects on your plants are aphids. You can spray them off with a hose, or try insecticidal soap. For more information, see the following article: Aphids in Home Gardens.
