Moved
Moved from Gall Midges.
From Dr. Gagne: "The gall midge from Salix is a female, probably of Lestodiplosis. Larvae of these are predators, often in galls. I do not know the gall. Could it be a Pontania sawfly?"

How big is the gall?
Gagne (1) just mentions one type of spherical midge gall on willow leaves, and it is about 2 mm in diameter. This looks a lot bigger than that, though, yes?

No clue then!
Maybe it's in Ron Russo's book...
