Queen Anne's Lace and Ant 1

Believe it or not, you're looking at a wild carrot here, or rather, its flowers.  Daucus carota is best known in the U.S. as Queen Anne's Lace, and domesticated carrots are cultivars of one of its subspecies.  It is strangely considered a noxious weed by the USDA, despite the fact that its presence boosts tomato plant production and provides a microclimate of cooler, moister air for lettuce.  It also attracts wasps, but in areas where it's been introduced it does so in far fewer numbers; some may still see this as a problem, but wasps are pollinators, and many do hunt destructive insects.  An ant forages atop this cluster.
