Hey /an/,What the fuck are these things?I'm not sure what kind of trees they were on, but it was some kind of oak. It was in Reno, Nevada. They came off easily, and were falling off the tree constantly too. They were pretty hard too, but you could crush them between your thumb and forefinger easily enough.Halp, I must know.
Sorry for the shitty picture quality.
SOMEONE must know.
Those are plant galls.
They occur when a gall wasp stings the plant and lays an egg into it.Inside lives the larva of the wasp.http://en.wikipedia.org/wiki/Gall_wasp
