Identify this gall!

[urbpan]

The host plant is ground ivy (or creeping Charlie or Glechoma hederacea). Third picture show gall split open, to reveal a single maggot or wasp grub. Anyone know what this gall-making insect is?

Given that third picture I'd say it was an ex-gall-making insect.

Thank you! I've been needing that plant identified for about 20 years now.

That's funny! I just took your well-researched FB post and quoted it on LJ.
