It appeared to be false solomon's seal to me but then I started to second-guess myself. I knew the folks here would confirm that or not! Thanks much for the responses! FataMorgana

Pretty sure this is another Blue-grey Gnatcatcher.

I copied this as it was easier than typing it out. It applies to Ohio but should be good for Illinois as well. "The woodfrog is an example of an explosive breeder, a species that congregates in large numbers at breeding ponds for a very short mating season lasting only two or three days to a week. They become active in mid-March and remain so until late October. Spawning is accomplished in small temporary pools, swamps, or semipermanent ponds and takes place from mid-March to early April in northeastern Ohio. Woodfrogs often lay their clutches of eggs aggregated in a central location of the pond thereby forming huge rafts of eggs deposited below the surface of the water. Individual egg masses are globular in shape and measure 75-100 mm in diameter. Each mass may contain 1000-5000 eggs with each egg swelling to 6-7 mm in diameter upon hydration. The eggs hatch in 14-21 days, and transformation occurs 61-115 days following spawning. Woodfrog tadpoles are dark, nearly black, and transform the year they hatch at lengths of 38-48 mm. Recently transformed woodfrogs 15-18 mm in length may be found from early June through late July. Sexual maturity is reached in two years."

That quiz is cool. But it says that I sound like North Central. Don't know about that! When dh lived in NC the people there thought he was from Virginia. Apparently our Cdn accent sounds like Virginians....
