La semaine dernière, l'IPBES a fini une série de réunions d'information préalables au lancement de l'évaluation des entreprises et de la biodiversité avec diverses parties prenantes au Royaume-Uni et à Paris. @steveormerod.bsky.social @thebotanics.bsky.social @frbiodiv.bsky.social

Nous remercions chaleureusement Arup, @steveormerod.bsky.social , @thebotanics.bsky.social et @frbiodiv.bsky.social d'avoir organisé ces sessions très enrichissantes. 🏡🧪 💡 Pour en savoir plus, consultez le document préparatoire de l'Évaluation (en français) : ipbes.canto.de/b/OLTM7

Brindled Green: Dryobotodes eremita Dryobotodes refers to feeding on oak and ‘eremita’ to the hermit-like behaviour of the larvae which isolate themselves inside developing oak buds #mothsmatter #teammoth

Merveille du Jour: the first of the autumn. Griposia aprilina - referring to the ‘April green’ colour even though this is an autumn moth #MothsMatter #TeamMoth

Black Rustic: Aporophyla nigra The most gothic of autumn moths. #mothsmatter #teammoth

Last week we visited the #freshwater #LongTermExperiment #LTE site Llyn Brianne in #Wales & met with @steveormerod.bsky.social from Cardiff University & @maplebay.bsky.social so it could be filmed for a #VirtualReality #VR experience! Learn about Llyn Brianne: bit.ly/LlynBrianne 🌏

Pink-barred Sallow - the first of the autumn Xanthia (= yellow) togata (= reference to a purple-striped toga worn by senators of ancient Rome) #mothsmatter #teammoth

The 2nd Clifden Nonpareil for the Cardiff garden - last caught 8/9/23. The expansion in range and numbers looks rapid: not even indexed in Glam Moths (2014). Bluesky had 33 UK mentions in the last 7 days alone on walls, attics and traps including Bridgend and Whitby #mothsmatter #teammoth

UK is well on course for losing Willow Tit, Spotted Flycatcher & Wood Warbler as breeding species in our lifetime. Wood Warbler already virtually gone from England. I think Willow Tit would be first extinction of a resident bird since Capercaillie in 1700s or White-tailed Eagle in 1918. #ornithology

Opportunist… #mothsmatter #teammoth

Large Ranunculus, Cardiff, 21/09/25 #Polymixisflavicincta #MothsMatter #TeamMoth

The Vestal - from last night here in Cardiff. The 5th for the garden in 13 years and last trapped in September 2023 #mothsmatter #teammoth @migrantmothuk.bsky.social

🌊 One-quarter of freshwater species are at risk of extinction, warns the IUCN Red List. From crabs to fish, these creatures are vital for ecosystems and human livelihoods. Pollution, habitat loss, and invasive species drive this crisis.🐟🦐 📷 IUCN 🗞️ iucn.org/press-releas...

A special day at @cardiffuni.bsky.social as we and #WelshGovernment hosted the UN @ipbes.net team in a Q & A session with representatives of Wales’ environmental community on the forthcoming #BusinessAndBiodiversity assessment due 09/02/26 #IPBES12 #BizBiodiversity #ForNature #AllJobsNeedNature

Box Tree Moth less abundant so far this year. This one was the first this month in what should be peak flight period that runs here in Cardiff through September and October. #MothsMatter

Palpita vitrealis in last night’s trap here in Cardiff: the only one this year so far #MothsMatter #TeamMoth #JasmineMoth #OliveTreePearl @migrantmothuk.bsky.social

Out yesterday with Ben Sykes of the @ect-uk.bsky.social to create a virtual/360 tour of our Llyn Brianne Stream Observatory system - aided by Gerjohn and Julia van den Bosch @one-cardiffuni.bsky.social @freshwaterbio.bsky.social www.cardiff.ac.uk/llyn-brianne...

Large numbers of southbound hirundines today over Cardiff’s #RoathPark Lake and under low cloud: mostly Swallows and Sand Martins with a few House Martins #ornithology #migration

Every year I have a Robin who wants to raid the moth trap. This year it’s this first autumn juvenile - still moulting way its ‘3J’ plumage… #mothsmatter #teammoth

Academic authors, here's a peek into the black box of journal publishing from an journal editor if you can bear it:

The #RoyalMail last week launched a set of stamps celebrating the UK’s wild and domesticated ducks for which I helped with images and accompanying text. We wanted to raise the profile of these stunning birds and their aquatic habitats. More here: shop.royalmail.com/special-stam...

First Dark Sword-grass of the year for our Cardiff garden. A total of 16 in previous years. #mothsmatter #teammoth @migrantmothuk.bsky.social

Pretty serious cyanobacterial (= blue-green ‘algal’) bloom on Cardiff’s #RoathPark Lake still continuing. Reflects low flows, high summer temps and misconnected sewers in the catchment that bring nutrient-rich water. The risks are well signalled around the lake

The 4th Maiden’s Blush of the year here in our Cardiff garden - doubling all previous numbers. Gives me the chance to brag about sponsoring then in the @savebutterflies.bsky.social Atlas… :) #mothsmatter #teammoth

Would be interested in observations and insights from other moth trappers and recorders 👇

What's happening to Large Yellow Underwings? In August here they typically average 55% of my nightly catch, but in 2025 have provided just 20%. Previous lows in 2022 (26%) and 2013 (23%) were also v dry summers. This is an abundant moth and probably important in food webs #mothsmatter #teammoth

Hirundines (mostly Sand Martin), Noctules (in this clip) and even a very late Swift tonight over Roath Park, Cardiff. Bruce Springsteen (Western Stars) on in the background

V quiet moth night. This Cypress Pug was the only species of note: they’ve been regular here in suburban Cardiff through all years of trapping as one of the four most commonly caught pugs #mothsmatter #teammoth

Two highlights from last night’s moth trap: Four-spotted Footman and The Gem. The Four-spotted is our 1st, and has a restricted distribution in Glamorgan. The Gem was our 2nd - first caught on 25/06/24 #mothsmatter #teammoth @migrantmothuk.bsky.social @sewbrec.org.uk @daveslade42.bsky.social

Grape harvest already underway around around the famous Beaune villages - much advanced by this year’s hot, dry conditions

Bedstraw Hawk-moth caterpillar today in the upper Saas Valley, Swiss Alps. So large I could barely get 80% of it in focus. #Hylesgallii #mothsmatter #teammoth

Grass of Parnassus: Murren, Swiss Alps #Parnassiapalustris

This Southern Hawker somehow managed to complete its life cycle and emerge out of mint-dominated garden pond. They’ve been regular here - but this is quite an achievement

The air over the garden thick with #mayflies this morning: Cloeon (probably C. dipterum) aka Pond Olive #mayfliesmatter

Macromoth species richness here in suburban Cardiff is near its peak in July despite the typical annual fall in numbers (though my actinic never gets the same large catches as MV traps elsewhere). As for July 2025? Mostly average. #MothsMatter #teammoth

Moths of late summer: Singled-dotted Wave and Scalloped Oak, and a look at what evolution can do with scales… Each comes from an individual scale-building cell as the pupa develops. #mothsmatter #teammoth

Saying farewell today to our long-standing supporter of students and staff, and behavioural researcher of birds and ‘non-birds’, @robthomasbirds.bsky.social as he moves to new worlds. I once heard him sing ‘Calon Lân’ on the banks of the Volga, and even the sturgeon stopped to listen…
