Knopper Gall
Comments(2) # Knopper Gall london e17

The Knopper Gall is not something that one might find on a Dire Straits guitarist finger but rather a wonderfully walnut-evoking growth on an acorn. So, when I was talking about oak trees not producing acorns every year in an attempt to disrupt the life cycles of acorn-predators, apparently I wasn't just talking about Squirrels and Jays. Like the Oak Apple and Oak Marble galls also found on Oaks these are the result of a gall wasp, Andricus quercuscalicis in this case, and here the bizarre life cycle of this little wasp requires both our English Oak and also the Turkey Oak. You will, I'm sure, be glad to learn that this is not an acorn from the LDNP Oak but rather one from the Waterworks Nature reserve where we also found the Myxi rabbit.....hmmm.... Canon PowerShot G9
