Oak galls - Andricus dimorphus

Oak galls - Andricus dimorphus
Washington County, Ohio, USA
October 6, 2012
Red galls on an oak leaf near some sandstone cliffs.

Moved from ID Request.
In the future, make sure you get a photo of the whole leaf & other identifying features if you don't know what kind of oak it is. I happened to recognize this one, but for unknown galls knowing the oak species is very helpful and sometimes essential.

Thanks Charley. I was trying
Thanks Charley. I was trying to split the difference between tight cropping for BugGuide photos vs. trying to include as much of the leaf as I could.

Plant photos
You can always add one or more linked photos that can be frassed once the host plant is ID'd. We even have a place where unidentified host plant photos are temporarily stored, here.
