oak gall

Amphibolips quercusinanis


This puffball-type gall is a little over an inch across, spotted and thin-skinned, resulting in a satisfying crunch when stomped (from a kid's perspective, at least).


Bottomland with mixed forest of oak, ash, bigleaf maple, etc. The insect responsible for this gall sets up housekeeping on the oak leaf.


It's full common name didn't seem to fit easily above: It's the 'Larger Empty Oak Apple Wasp.' I guess that makes these galls actually 'oak apples'. I've never seen (or at least recognized) the wasp that's responsible for these.

Nice! Almost looks like a piece of fallen fruit.
