Vein Pocket Galls (Macrodiplosis majalis) on Scarlet Oak (Quercus coccinea)

Galls growing on the veins of the underside of an oak leaf. They look kind of disgusting to me...like pustules!

The Macrodiplosis genus is still not well-described, so it is always possible that this is another species. Visually, it is a match on BugGuide.

Gorgeous shot! They look like little brains ;P.

I found some galls last year that I thought might be vein pocket galls, but I wasn't able to get very far with an ID. What do you think:

  This is a tough one for sure. I would assume a vein pocket gall, but I'm not sure. :/ Hmmmm. Posted 5 years ago
