Photo above is of a Green Dragon (Arisaema dracontium). Green Dragon plants have only one leaf, which is subdivided into leaflets in a horseshoe arrangement.
Photo below shows fruits of the Green Dragon which turn red, when they ripen in late summer.
We saw this same plant blooming here at Grand River Park on June 6, 2011.

Flowering Rush (Butomus umbellatus)
We saw lots of insects, the one below was different.I think this is a Beautiful Wood-nymph (Eudryas grata) or a Pearly Wood-nymph ( Eudryas unio).
