Oak Apple

Cool find! This is indeed an Oak gall. This particular gall is created by a type of wasp. Did you happen to open it up to see what it looked like inside? There are a couple of options for this. Here is the Bug Guide page for Genus Amphibolips, which is most likely the type of wasp that made this gall: http://bugguide.net/node/view/39773/bgpage It's very likely Amphibolips quercusinanis, Larger Empty Oak Apple Wasp. http://bugguide.net/node/view/240411 This spotting belongs in the Arthropods section. You could also add this to a couple of missions!
