Arizona Oak Galls, Part 2

Gall #2 is a fancy cup-shaped one found on the undersides of leaves, sometimes in clusters.

A month after I collected them, the galls (kept in a tightly sealed vial) had become covered with mold, but a single wasp chewed its way out of one of them.  It was dusty and acting a little drunk when I found it.

About Charley Eiseman

I am a freelance naturalist, endlessly fascinated by the interconnections of all the living and nonliving things around me. I am the lead author of Tracks & Sign of Insects and Other Invertebrates (Stackpole Books, 2010), and continue to collect photographs and information on this subject. These days I am especially drawn to galls, leaf mines, and other plant-insect interactions.
