This wild grape leaf is liberally covered with these growths. I'm guessing some kind of gall?? Also testing out my cropping/posting skill.

I think that's called grape tube gall. I'll see if I can get some info for you.....

BTW, great photo.

"The midge Cecidomyia viticola Osten-Sacken is responsible for the formation of the grape tube gall, a conical red or green leaf gall 1/4 inch long."

Thank you- I will relay your praise to the real talent, my Canon A 710 IS, which can take awesome pics or blurry ones and I'm still not sure what I do different. Anyway, that description fits.
I will certainly add this pic to Bugfiles if an admin likes it.

sallyg, I agree that these are the galls of the Grape Tube Gallmaker (Cecidomyia viticola). I have created an entry for it in BugFiles here: http://davesgarden.com/bf/go/4736/

Please add your image,

Kennedy
