Ivy Bee in sunshine where else but on ivy, in the company of a ladybird, and visiting a shady sandy bank. Almost certainly not the same bee! 😉

Good to have it growing wild. The only example I know is a small tree in Cambridge Botanic Garden.

Leaked video from speech to Tech bosses at JP Morgan Tech Stars event appears to show Chancellor Rachel Reeves boasting of a "good relationship with the developer" as one of the rarest creatures in Britain "some snails on the site that are a protected species or something" could pay the price.

Rachel Reeves clears planning blockage amid ‘good relationship’ with developer

Exclusive: Chancellor says 20,000 homes were being held up due to ‘some snails that are a protected species or something’

Nice photos! I was going to say it would be a good idea to put that in iRecord but it looks like it's already there since 23 September.

"Rachel Reeves unblocked a development of 20,000 homes that were being held up by a rare snail, after being approached by a developer with whom she said, 'we have a good relationship'

Not only stupid and ignorant, but crooked with it

Indefensible

Yes, mine's in iRecord already. I've seen it in a field edge in Suffolk Brecks. Sometimes these have 'game bird' seed mixes and I wonder if it's a common contaminant?

Roger_TL45Y @rogerhorton.bsky.social · 1d

They seem to turn up as contaminants in the seed of other plants. Once they grow they are attractive enough to avoid being weeded out. No idea how this one cam to be where it was. I'm sure botany recorder for VC27 East Norfolk would be interested in your plant!

In an otherwise barren verge around a supermarket carpark in Newmarket Rd #Cambridge surprised to find Apple of Peru, Nicandra physaloides, looking as though it has been carefully tended! 💜🖤🤗

Congratulations! Here’s a photo I happen to have on my phone of what I think is Peltigera rufescens #Lichen at @suffolkwildlife.bsky.social Lackford Lakes. ‘Where it always is’ on dry sandy soil, and looking pinkish in the sunshine.

There's a huge dead tree trunk in the local park that's not as photogenic as this autumnal Sweet Gum, Liquidambar styraciflua, in front of it. 🍒🏘️ Cherry Hinton Hall #Cambridge #ThickTrunkTuesday

My mum was fond of it too perhaps because it always featured in late August holidays to the West Country. I’m a bit annoyed that it now gets called Crocosmia!

Roger_TL45Y @rogerhorton.bsky.social · 2d

Same era: Montbretia. French botanist Antoine de Montbret in Napoleon's 1798 Egypt expedition & died there of plague, 1801. Fellow botanist Delile survived expedition & named 'Gratista Montbretie' in his honour. What is now Monbretia = Crocosmia x crocosmiiflora, garden origin 1880.
