No #waxcaps on this, or any of my other usual sites so far this year. This slope has had a good range of species in recent years, including ballerina waxcap. Is anyone else seeing this ? South facing slope with severe grass die off from June to the end of August.

Cofnod #RecordOfTheWeek is this Wall (Lasiommata megera). Recorded at Mariandyrys by Mark and David. @sewbrec.org.uk @bispowys.bsky.social @wwbic1.bsky.social

Spore prints can be beautiful. But not always, in my case at least, helpful for an ID!

Great to have been out surveying with @ecology-digest.bsky.social and @theponker.bsky.social on the Yorkshire Dales for a few days. Rounded 'busman's holiday' off vacuuming another saturated Sphagnum lawn at 650 m altitude, and getting challenged by a Heather Chicken @britishspiders.bsky.social

Cofnod Rockpooling Course was great, even if the venue had a "War of the Worlds" vibe about it! Thanks Paul and Yolanda for such an informative day. @sewbrec.org.uk @bispowys.bsky.social @wwbic1.bsky.social #nudibranch #seaslug

#RecordOfTheWeek today is this fantastic Spurilla neapolitana, also known as the 'hair curler' sea slug spotted at Oxwich by Tate Lloyd, and is new to Wales! The first UK sighting was only last year in Cornwall. Many thanks for the record & photo, submitted via iRecord. irecord.org.uk

Now we're outside the bird nesting season, our peatland restoration works are back underway at Cors y Sarnau Nature Reserve. Together with the help of three playful Carneddau ponies, we're removing saplings and scrub to keep the peat bog habitat open. 💚

Rainbow Sea Slug Babakina anadoni with its prey the Hydroid Candelabrum cocksii - great find by Daisy Wood, Wembury Point, Devon at the weekend. The Olympus TG cameras are great for rockpooling able to withstand impact of being dropped on rocks and also completely waterproof - I use at TG6

Cofnod #RecordOfTheWeek is this Odiellus spinosus Harvestman by SueH. Easily recognised by its chunky body, short legs and distinct trident on the front margin of its head! Very much a lowland species. @britishspiders.bsky.social @megabunus.bsky.social

Thomas Pennant's (1726-1798) body of work spanned natural history, antiquities and travel. To celebrate his tercentenary, we've added his correspondence and catalogues to our Digital Special Collections: buff.ly/ZFULOe0. #Manuscripts #18thCentury #HistoryOfScience #HistoryOfNaturalHistory

Do you have nature records in notebooks that you never look at and wonder what to do with? I've transcribed 10,000 records from the 1960-70s from a Welsh ornithological legend into @birdtrack.bsky.social and @cofnod.org.uk. And it was fascinating... #BirdingWales www.cofnod.org.uk/news/natural...

@britishspiders.bsky.social @tylanberry.bsky.social @cofnod.org.uk A quick stop-off in Wales, to find a spider that I've yet to see in England. It always surprises me just how well such a big spider can 'hide in plain sight' on bare stone Arctosa cinerea is always a sight to behold

New Thinozercon trip in Wales. This time a very successful trip with LOTS of amazing little critters. Everything from Crustaceans, Hemiptera and velvet mites in one location. Wales has such amazing #ukwildlife 🌿🧪 #inverts #bugsky #entomology Blog here: rosariolebronentomology.com/thinozercon/...

Cofnod #RecordOfTheWeek Violet Bramble Rust (Phragmidium violaceum). Spores photographed and recorded by TonyC in Denbighshire. This fungus occurs on Bramble, and forms impressive pock-marked purple swellings on stems! @sewbrec.org.uk @bispowys.bsky.social @wwbic1.bsky.social @britmycolsoc.org.uk

Totally magic and incredibly beautiful! Not 1 but 2 adult #Convolvulus #Hawkmoths #Agrius convolvuli encountered on #AngleseyCoastPath between Traeth Coch and Penmon this morning; Occasional/scarce migrant from S Europe/Africa; records submitted @cofnod.org.uk #mothsmatter #moth #TeamMoth #Wales

Cofnod #RecordOfTheWeek is this Llandulas Bee Wolf (Philanthus triangulum) recorded by RobinS. @sewbrec.org.uk @bispowys.bsky.social @wwbic1.bsky.social

#RecordOfTheWeek today is a Sponge Crab (Dromia personata), spotted in Oxwich by Zoe Foster. This species has a symbiotic relationship with sponges, which provide the crab with camouflage while the sponge gains protection from predators. Many thanks for the record & photo sent via LERC Wales App.

Timothy Tortrix caterpillar on Skullcap #WildWebsWednesday #TeamMoth

A mite last seen 39 years ago. We will be walking the Welsh shore looking for it, and posting as we go. The site now has a live blog, a map of everywhere we have searched, and a Welsh option. I can't speak Welsh, but this is Wales. It needed a Welsh option. Thinozercon is out there. #inverts 🧪

Years ago I learnt from Adrian Spalding that the Sandhill Rustic moth Luperina nickerlii can swim! Tried this out on Anglesey this week. It lives in coastal dunes and salt marshes and the females rarely fly so presume this helps if caught Out by spring tides.

I'm invariably wrong with my spider id 🙄 but I'm thinking these might be male & female Four-spotted Orb Weavers, Araneus quadratus. Spotted just now in my #Anglesey meadow for #WildWebsWednesday @cofnod.org.uk

Beautiful early morning light Mynytho Common, Llyn Peninsula, North Wales

Creating wildflower meadows 🌼 Recently, our staff and volunteers spent the day collecting and processing wildflower and grass seed from our magnificent meadows at Caeau Tan y Bwlch Nature Reserve. The seeds will be used to create and restore other meadows at various sites on the Llŷn Peninsula. 💚

Sketches of male and female Scalloped Hook-tip Falcaria lacertinaria A beautiful dead leaf mimic Trigonos, Pentlle, Snowdonia North Wales

A very scenic spot to run my light trap this week with Snowdonia as a backdrop. Canary-shouldered Thorn Ennomos alniaria the commonest of 60 plus species caught Trigonos Pentlle Snowdonia North Wales

A good year for Hummingbird hawkmoths in North Wales. Usually spot one every few summers but four so far this year @cofnod.org.uk @savebutterflies.bsky.social

Two for #WildFlowerHour from yesterday's walk in #Eryri National Park: (1) one of around 40 Common Butterworts growing from a vertical rock - the photo is the right way round! (2) Yellow Water-lilies on Llyn Cwmorthin, a fairly scarce flower in the uplands of North Wales. Both now on @cofnod.org.uk

#RecordOfTheWeek today is lovely Little Owls (Athene noctua) recorded in Gwent by Chris Blyth. Many thanks for the record and photo, submitted via www.sewbrecord.org.uk.

Great to finally see Cheiracanthium pennyi (Endangered & Nationally Rare). Known site, but always useful to confirm continued site presence. One of the spider road-trip highlights @britishspiders.bsky.social

After flitting around like a demented mosquito desperately following the butterfly determined to get a photo, so pleased when it finally landed. My first Clouded Yellow sighting in 9 years. #Aberffraw #Anglesey #WildWebsWednesday @savebutterflies.bsky.social @cofnod.org.uk

5-spot Ladybird, Araneus angulatus, Attulus inexpectus and Badumna longiqua. Just a few photogenic highlights from a week-long spider recording road trip. @arachnoteg.bsky.social @bugsnstuffcom.bsky.social @wwbic1.bsky.social @sewbrec.org.uk @britishspiders.bsky.social @vc40ladybirds.bsky.social
