Galls - Phylloxera caryaeglobuli
Cross Plains, Dane County, Wisconsin, USA
June 11, 2009
I picked some of the leaves from a hickory with these galls and placed them in a container several days ago. Today when I checked the insects had cut their way out of the galls. The galls look a bit shriveled here but they were similar to this one when I picked the leaf from the tree.

Phylloxera galls
The galls are mostly around 5mm in diameter. The first leaves of the hickory trees were covered with these galls this spring.
