I believe you can tell them apart by the stem. Queen Anne's Lace has a hairy stem and smells like a carrot. Poison Hemlock (which I think is what is in the image) does not have a hairy stem and does not smell like carrot.
It was in a small creek just south of and exit ramp off of I-94 in Highland, Indiana. The creek flows into a larger retention pond. There were many, many frogs hopping into the brush as I walked closer to take the pix.
