Galling through the Oaks

Those little things you might see on oak leaves at the end of summer are Galls. I saw several different types of galls on the smaller oak trees along the Ferrari trail and show three of the most common. These are plant growths and are the temporary homes of tiny wasps while they metamorphose.

We thought we’d give our oak galling another go, and drove over to Lincoln Hills’ Canyon Oaks trail which is next to Ingram Slough. There are several types of oaks there and even an interpretive sign to help with identification. The oaks have kindly provided a few additional galls.
