The new Red List for Vascular Plants published this week by @bsbibotany.bsky.social highlights the serious decline in Britain’s freshwater plants.

We are returning once again to Hull in 2026 for the City Nature Challenge! Join us & make observations throughout the city between 24th April - 27th April 2026 using @inaturalist.bsky.social. Our project is already up and running - join here for updates: uk.inaturalist.org/projects/cit... 🔎📱

The new book 'Spiders & Harvestmen of Yorkshire - An Atlas', by Richard Wilson, is out now and available for purchase: www.naturebureau.co.uk/spiders-harv... Over 384 pages, the book describes the history of spider and harvestmen recording across Yorkshire and its varied landscapes, with mapping.

Artificial lighting along the Pembrokeshire coast disorients young Manx Shearwaters, leading them to crash inland and become stranded. Manx Shearwater Rescue Pembrokeshire, a local volunteer group, helps collect and safely return these vulnerable seabirds to the sea. bit.ly/4oqW8qQ

Often overlooked, small water bodies - streams, damp ditches, small bogs, ponds - support more rare species compared with larger habitats while high-quality ponds support about 2/3 of all freshwater plant + animal species in a landscape. 🧵 1/4 freshwaterhabitats.org.uk/news/start-w...

Anyone know what this is? Found on underside of Sycamore leaf at Cayton Wood, a National Trust site just south of Scarborough, on 11th October during a visit by Hull Nats.I One proposal has been the moulted cuticle of a hoverfly larva. @ynuorg.bsky.social

Wow!

In the lesser water-boatmen (true-bugs of the family Corixidae), the expanded front tarsal claws are known as palae. The shape of the male pala and the arrangement of pegs on the inner surface are important in separating similar species. This is Sigara falleni with its broad, shovel-like palae.

@tc271.bsky.social for info. At Leconfield DST I found this species in Swan Mere last month & in 2022. Also Whydham Lake in 2022. Are these both fishing lakes?

Another Water Beetle. Noterus clavicornis. Leconfield DST 21 Sept. c. 6mm long. Prosternum with ridge and narrow neck

c.12 mm Water Beetle from Leconfield DST 21 Sept. Keyed out using Friday to Ilybius fenestratus. Very narrow lateral part of metasternum. @palustris.bsky.social

No longer needed for farming, they remain part of the landscape’s story and, thanks to groups like the Yorkshire Wildlife Trust, are being restored as quiet havens for wildlife. Image courtesy of Yorkshire Wildlife Trust. See their article at www.ywt.org.uk/wolds-dew-po... 2/2

Our species taking spot #93 in our #YorkshireIn100Species series is the Brown China-mark moth, brought to us by Dick Shillaker. This moth has an intriguing life history, being one of only a small number of species with aquatic larvae! www.neyedc.org.uk/100-species/... 💧

Really cool story about long-distance pollen transport by migratory hoverflies. The actual research paper is here: doi.org/10.1111/1365...

This is the second time this year I have Parent Bugs breeding on Silver Birch locally in East Yorkshire. Is this just a chance finding or a known association @rockwolf74.bsky.social ?

Weekend #Plankton Factoid 🦠🦐

...having had a look, the only aphid usually found on duckweed (Lemna spp.) is Rhopalosiphum nymphaeae (influentialpoints.com/Gallery/Rhop...), a species that host alternates between Prunus and a variety of water plants. These were mostly immatures.

Pick of the trap was this stunning Cosmopterix pulchrimella. A Pellitory-of-the-wall feeder & first discovered in Britain in 2001.

We caught some fantastic footage from a camera trap set up the night before our wildlife recording day in Hayton - a trio of otters! 🤩 We're recording wildlife in Hayton as part of the Live Labs 2 project, which you can read more about here: www.neyedc.org.uk/updates-insi...

Join NEYEDC & East Riding of Yorkshire Council in Hayton on Tuesday 2nd Sept for a wildlife recording day, part of the Live Labs 2 project! Alongside recording, we'll be hosting a moth trap opening, sharing what the project has found so far & showing how you can get involved: www.neyedc.org.uk/c2n 🔍

A bit gruesome. Larva of parasitic wasp attached to 7-spot ladybird. Presume wasp is Dinocampus coccinellae; larva of this species emerges from inside ladybird, then spins cocoon & pupates under ladybird partially paralysed by wasp. This ladybird had been in same spot for several days.

Magnificent Alder on South Cliffe Common, SE Yorkshire. First blotch mine I think caused by Small Alder Midget. I dont know what caused the 2nd apparent blotch mine. Any thoughts welcome @vc28wildlife.bsky.social. Seen on recent @ynuorg.bsky.social excursion.

Could this Potamogeton be P. polygonifolius? Rather pointed leaves and in ditch bordering a sandy maize field (once heathland) and close to existing heathland (Hotham Carrs). 9 August @ astridbiddle.bsky.social. YNU VC61 excursion @ynuorg.bsky.social

Could this be leafminer damage in Buxus? East Yorkshire garden today @vc28wildlife.bsky.social
