Oak Gall

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.
