Insect gall on grape leaf

Grape Phylloxera

Description:

I have no idea what this is, perhaps an insect or a fungal infestation of a what I think is wild grape leaf. Any help with identification would be appreciated.

Habitat:

Border of woods in southeastern PA USA

Neat find! This would be a good addition to my new mission for Arthropod Galls!

Thank you for the suggestion KarenL.

And thank you dandoucette for the link. I haven't read the whole article on Phylloxera yet, but from what I did read in scanning the wiki article, it does sound like that's what it is. I had never heard of an insect gall before!

This is an insect gall, possibly caused by Grape Phylloxera.

Looks like some kind of gall - maybe grape tumid gallmaker?
