How is this created and so even and concentric.
These spiders eggs? appeared overnight.

Found this tree creeper in the office this morning.look at the claws on that!

I'm steering well clear of Hay on Wye!

My NON-expert thought is that they are concentric mould patterns on the apple. I've seen a few instances of concentric mould patterns, but I don't know what the actual mechanism is that creates those patterns. Maybe something similar to how fairy rings are formed? Fairy rings that I've seen have only one circle, but apparently sometimes multiple concentric circles can occur:

I don't know if this is of any use, but here's an older discussion about it on another forum: https://www.thenakedscientists.com/forum/index.php?topic=49171.0

Fascinating indeed, here's the answer it would seem. From your article @Blue Chips .

Oh how pretty! Its Sclerotinia fructigena by the looks of it – I have some growing on pears in my greenhouse for an exhibit especially for UK Fungus Day at the Cambridge Science Centre this weekend! The fungus causes brown rot of apples, pears and some other fruits with infection caused commonly through wounds but sometimes insects and earwigs – these buff coloured pustules are conidia (asexual spores) of the fungus and they often appear in concentric zones. Sporulation is stimulated by light and adjacent zones correspond to daily periods of illumination – the fungus mycelium grows out in a concentric pattern and light stimulates sporulation - hence the concentric pattern of pustules on the fruit. Hope this helps Chris!

I see the occasional tree creeper round here, as well as nuthatches. I think they are the only two U.K. birds that can walk down a tree trunk as well as up, but I could be wrong.

I’ve witnessed it.
