Taken on Aug. 1, 2014

This photo shows a white snakeroot plant in bloom; it was one of the earliest plants to bloom in the surrounding neighborhood, blooming a few weeks before many of the plants of this species started.

This photo shows clear views of the trails left by the larvae of a leaf miner, possibly Liriomyza eupatoriella.
