Two different galls close together, both on goldenrods. The top shaggy one is called a bunch gall, caused by Cecidomyiid midges. The round, ball-shaped one below is made by the goldenrod gall fly, a large attractively patterned fly in the Tephritidae family, the fruit flies. Larvae of the latter fly, provide food for birds and animals through the fall and winter, and you'll often find the galls either chewed in half or with large holes in them.
