Knopper Galls

Knopper galls

Hundreds of knopper galls are scattered beneath the oaks in Nostell Park. On some you can see the way that the acorn has been transformed into the home and the food source for the larva of the gall wasp Andricus quercuscalis. The acorns have stalks, botanically penduncles, so these are the acorns of the common or pendunculate oak, Quercus robur.

It’s the asexual generation of this gall wasp that produces the knopper gall; the alternate sexual generation produces tiny galls on the male catkins of the Turkey oak, Quercus cerris. Turkey oak acorns have ‘mossy’ cups, that remind me of the furry Russian hat that Ivan the Terrible might have worn. There are several Turkey oaks at Nostell.

Bracket fungus

This species of bracket fungus is sprouting on deciduous stumps in the woods around the lakes.

The head gardener is adding wire mesh to the newly restored iron gate to the walled garden.

“Is that to stop the ducks getting in?” (It’s been a good year for the mallards on the nearby lakes).

“No, rabbits.”

“I worked on the film of Watership Down, so I’m always rooting for the rabbits.”

“There’s plenty of grass out there!”

This is a first for me: writing and uploading a blog post on my iPad as my studio is out of action for a couple of days and my wall-mounted iMac is taking a well-earned break, lying on the bed in the back bedroom. We hadn’t realised that revamping the kitchen downstairs would involve taking up the floor upstairs in the studio to fit the new LED lights. This gave me the ideal opportunity to get Simon, the joiner fitting our kitchen, to replace the chipboard floor in the studio with tongued and grooved boards. It will all be worth it and the old kitchen is already looking more sparkly.

Sketchbook

My scanner is out of action for a few days too so here’s an iPad photograph of the latest spread in my A6 ‘Travel Journal’ sketchbook with sketches from a rainy morning at Nostell, a train journey to Leeds and from the centre of Wakefield.
