Gall on bitternut hickory leaf, made by Phylloxera

A small bitternut hickory sapling had a number of these galls on them. Most had opened, as with this one, and inside I found a huge number of Phylloxera insects inside.

I hope this sort of thing is symbiotic and the host gets something out of the deal!

Looks like over-ripened fruit.

I never knew these had bugs in them. Ignorance is bliss. :) Just kidding. Excellent and educational photo. V.

I thought it was a shrivelled skunk cabbage flower with bugs in it. I have never seen inside a gall before. Great photograph.
