🐌🎉 One year ago this week, the Pyrenean Semi-slug (Semilimax pyrenaicus) was discovered new to Britain — found on Cwmaman Tip, near Aberdare, Rhondda Cynon Taf. A small species, but a big moment for British wildlife. (1/7)

✨ Golden-eye moment! 💛 Out in the Cynon Valley today, our team found Golden-eye Lichen (Teloschistes chrysophthalmos) on hawthorn at the former Aberaman Colliery. Once Critically Endangered, this Mediterranean species is now spreading - it was first recorded in Wales in 2015 on coal spoil.

🎄 Merry Christmas & Happy New Year / Nadolig Llawen a Blwyddyn Newydd Dda 🎄 Thank you to all who’ve supported us through our transition to Glo i Natur CIC 💚 2026 is shaping up to be an exciting year - with events, training and new projects ahead. Keep an eye on our socials for updates!

We recently visited Parc Calon Lan & the former International Colliery in Blaengarw. Once coal spoil, these sites now offer space for the community and support rich wildlife, including threatened species like Small Pearl-bordered Fritillary. A powerful example of nature reclaiming industrial places.

We usually showcase the plants, fungi & invertebrates of coal spoil sites - but here’s some of the hidden life too 🐭 Wood Mice sheltering under a metal sheet at Darren Fawr Tip in the Garw Valley. Coal tips: full of surprises, even in winter. #GloiNatur #CoaltoNature #SouthWalesValleys

Tufa springs on coal tips 💦 These rare micro-habitats form where water passing through coal spoil picks up calcium - likely from ancient marine bands - and deposits it at the surface. Unusual in the acidic Valleys, and vital for specialist wildlife like soldierflies. #GloiNatur #CoaltoNature

Great to speak with the Nature Restoration & Forestry students from Black Mountain College in Treherbert today about coal spoil wildlife. Sharing this knowledge is vital - inspiring future practitioners to recognise the biodiversity value of these sites. 🌿💚

We've had nearly 300 bookings for our talk on the Clubmosses of Britain and Ireland by Fred Rumsey next Tuesday evening (2nd December) and there's still places left! Book now for free (though donations towards our work are appreciated): share.google/lQL6JQ7E9SEQ...

Its that time of year again: a male Snow Flea, one of 3 seen yesterday in woodland on the Shrops/Herefords border. These 4mm relatives of Scorpionflies live in moss (esp. Polytrichum & relatives) & are winter active as adults. Not fleas of course but they can jump a bit.

Loving invertebrates + owning a log burner is a risky combo 🔥🕷️ I always check logs for stowaways, and tonight I rescued a beautifully camouflaged flatbug Aradus depressus from the fire 👀 It’ll be released onto dead wood in the garden to overwinter 🤞

Last night, Liam and Carys from Glo i Natur CIC joined the @wtsww.bsky.social Brecon Group AGM, where Liam gave a talk on the rich biodiversity of South Wales’ coal spoil sites - from Pennyroyal & Adder to the “Maerdy Monster”! Thanks for the warm welcome. #GloiNatur #CoaltoNature #CoalSpoil

It's bulb planting time! Bulbs make dazzling displays in containers or borders, and they’re also a great source of late winter/early spring nectar for butterflies and moths 🦋 Top 5 bulbs to plant: 🌷 Crocus 🌷 Alliums 🌷 Grape hyacinth 🌷 Winter aconite 🌷 Snake's-head Fritillary 📷: Rob Blanken

My first Snow Flea (Boreus hyemalis) of the winter at Cali Heath @yorkswildlife.bsky.social reserve today. Nice of her to pose out in the open on a fallen leaf, so didn't need to spend hours waiting for one to emerge from the Polytrichum moss! @ynuorg.bsky.social #Mecoptera #Boreidae #ukwildlife

1/3 Liam & Christian were in the Wyre Forest Coalfield today, where Liam was guest speaker at Worcestershire Entomology Day 🐞 Nearly 100 people attended!

🎉 Celebrating 10 Years of the Colliery Spoil Biodiversity Initiative 🎉 This December marks 10 years since the Colliery Spoil Biodiversity Initiative began its mission to change how people see South Wales’ colliery spoil sites — from barren relics of industry to thriving havens for wildlife. 1/3

Amazing moment seeing my first ever Purse Web Spider (Atypus affinis) at Broad Haven South Dunes last night (spotted by my colleague Christian Owen). This incredible species is more closely related to the tarantulas and trapdoor than to any other British spider! @britishspiders.bsky.social

Thousands of Ivy Bee (Colletes hederae) at Freshwater East, Pembrokeshire, yesterday. Amazing to watch them, especially the mating balls.

An opportunity of a lifetime for budding lichenologists. The National Trust and the Royal Botanics, Edinburgh are offering a PAID lichen traineeship in #Scotland! The work programme looks fascinating and a great opportunity to develop skills. Deadline: 3/10/2025. www.asva.co.uk/jobs/trainee...

🪲 Weevils! The UK boasts 600+ species, almost as many as birds! Join us on 13 Oct (7–8pm) for an entoLIVE with @markgurn.bsky.social to explore their ecology, habitats & quirky plant preferences. It is FREE!!! Don’t miss it! 🧪 🌎 🔗 Sign up here: www.eventbrite.co.uk/e/1491232379...

Callicera spinolae, the Ivy Hoverfly, is one of the UK's rarest hoverflies, as well as one of the most spectacular. This morning, I recorded a female on the Ivy in my S. Cambridgeshire. This is the 5th consecutive year that I have seen this wonderful fly in my garden, four days earlier than before.

Why do we have to fight to protect already protected areas? Coul is an SSSI - seems to mean nothing if you have money and want to build a golf course. We do not need another golf course. Please sign this petition to protect #nature and our beautiful home. #coul action.rspb.org.uk/page/166270/...

If you want to identify, well, anything, I recommend this post from @weevil-see.bsky.social. His choice of weevils to illustrate it is of course excellent, but it applies to everything from mushrooms to marsupials. This is how you can be a good identifier of things. [Link contains spider]

Marsh Gentian (Gentiana pneumonanthe) from Cors Goch National Nature Reserve, Ynys Mon (Anglesey), yesterday. Greatful to @northwaleswt.bsky.social staff for showing us this during our search for rare fen invertebrates.

Absolutely brilliant day on Ynys Mon (Anglesey) yesterday looking for rare fen Invertebrates with @naturambyth.bsky.social @natreswales.bsky.social @northwaleswt.bsky.social. Richard Gallon of @britishspiders.bsky.social was able to show us the nationally rare Sedge Jumper (Attulus caricis).

Sadly no Red Squirrels sightings at The Dingle/Nant y Pandy Local Nature reserve in Llangefni, Anglesey, this evening. Pleasing to find the barklouse Bertkauia lucifuga though, which doesn't appear to have been recorded in North Wales before.

Plenty of Shrill Carder Bee (Bombus sylvarum) workers seen on today's survey of a brownfield site in Cardiff - we're so lucky to have these beautiful bees in South Wales! 😍 Brown-banded Carder Bee (B. humilis) also present in abundance.

Brilliant day spent at Whiteford Burrows #Gower yesterday surveying for the scarce chalcid wasp Chalcis sispes on the saltmarsh, which parasitises Stratiomys larvae. We were fortunate to find 5 of the wasps and a few of their Stratiomys singularior (Flecked General) hosts. Survey conducted for NRW.
