Oak Leaf Saucer Gall
This saucer shaped gall is produced on the leaves of Oak trees by the gall wasp Andricus gigas.
These are not to be confused with a nest of wasp eggs but are actually leaf tissue induced to grow in this manner by enzymes supplied by the wasp when the egg is deposited. I have been unsuccessful at finding an egg by dissection and have to take it all on faith.
It would also be nice to get a photo of the wasp itself but I can't even find one on the internet much less a live one.
Maybe next year.
