Who is eating holes into these nettles? They look as though they have been peppered with grape shot. No visible culprit at Wimbotsham yesterday.

Time to day goodbye to my last stored apple. Didn't they last well? They came from an old tree near the lane.

I'll get its DNA analysed @niab-uk.bsky.social but could be an old variety, Yorkshire Greening - good for eating as well as cooking - aka Yorkshire Goosesauce, a tart condiment.

The Black Death’s counterintuitive effect: as human numbers fell, so did plant diversity New study finds that plant biodiversity collapsed in landscapes where arable production was abandoned during and after the Black Death era.

"The Black Death disrupted this [biodiversity] by reducing human disturbance. The result was a less patchy landscape and an overall loss in plant diversity. Diversity only recovered when extensive farming returned."

As seen springing on a matted road island at Bungay. As leaking up beside dog-irrigated lamp-posts. As waving little white hankies from brick walls

Lamps breeding streetline patches of darkness and sounds falling dead. Mist, breath, mist. Sweating bricks. Eine echt Werwolfstadt.

For added excitement while looking for bee-flies, check your local daffodil patches for the Daffodil Dung-fly, a spiny-legged fly that is in the dung-fly family but has nothing to do with πŸ’©

An avenue of oak trees appearing through fog across a damp, grassy field.

Something is infesting the Suffolk claylands with massing fog (through which one cannot discern a church tower 1 km away).
X-Twitter blames it on sinister chemtrail scientists.
The @metoffice.gov.uk blames it on Saharan dust.
I blame it on sea-serpents off Orford Ness.

Unfortunately I think the moss pads concentrate water leading to freeze-thaw erosion of tiled substrate.

Last summer Dunwich Greyfriars Trust swiped its grassland down to degree zero, even right up to the walls. Goodbye flowers, butterflies, grasshoppers - hello stubble and a thatch of dead stalks. Have promised to do things differently this year. Great Green Grasshopper recorded at the site.

Mosses play a lively part on the ecosystem of my roofs.
On the south-facing surface, Sparkly Petting-moss.
On the north-facing surface, Manky Mush-moss.
Both have robust populations of mites and water-bears for endless microscopic fun.
