Curly acorn cups

I’ve been noticing lots of very curly acorn cups strewn under oak trees the last couple of weeks. I could tell from the leaves of the trees that they weren’t either of our native oak species (the sessile oak and the pedunculate oak). I got a decent picture of a twig that had snapped off, and I’m pretty sure it’s a turkey oak. It turns out that the turkey oak is a bit of a pest, being well adapted to the acidic, sandy heathland soils where it displaces natural vegetation. It also hosts the parasitic Knopper Gall Wasp that attacks our native pedunculate oak and reduces its ability to reproduce.

Still.. very pretty acorn cups. 😉
