During the course of this year, I have come across quite a variety of plant galls in the Staple area. Here are two more on Field Maple leaves. I have collected these together on a page in the Walks and Wildlife 3K section of this website.

The cluster of red pustule galls here are caused by another gall mite Aceria aceriscampestris.

These solitary, round galls are caused by the gall mite Aceria macrochela.
