Exploring a coal spoil site near Aberdare today, we found the flat-backed millipede Polydesmus barberii.

This non-native species, first seen in Britain in 1995, has only recently been discovered in Wales. Today's find is just the fourth known site in Wales β€” and the third in the Cynon Valley!

Last night we visited Gelli Tips and were treated to a beautiful scene – the evening sunlight casting a golden glow over the tips, with the heather in full bloom. πŸ’œπŸŒΏ

We also captured some breathtaking drone footage that will feature in an upcoming video for Buglife’s Coal Spoil Connections project.

🟣 Berytinus crassipes & B. montivagus (stilt bugs)
🟣 Doratura stylata & Rhopalopyx adumbrata (leafhoppers)

Once again, colliery spoil is proving just how special it is β€” supporting species you won’t easily find elsewhere. There's real ecological value in these overlooked landscapes. πŸ’š

This year we've been working with the South Wales Trunk Road Agency to survey roadside verges for invertebrates around Merthyr Tydfil. Today we made our final visit to a very special verge in Dowlais. Comprising colliery spoil, it's proving to be a real hidden gem for biodiversity!

Back to Sirhowy Hill Woodlands today to continue the invertebrate survey. The reserve looked lovely, and great to see the bee hotels in use β€” even spotted a Wood-carving Leafcutter Bee (Megachile ligniseca) basking on one!

Among today's nice finds was the leafhopper Rhopalopyx adumbrata.

Incredible tufa springs seen at the former Pentremawr Colliery, Pontyberem, Carmarthenshire, today - clearly decades of tufa deposits! Around the springs was Delicate Soldierfly (Oxycera nigricornis) and Giant Lacewing (Osmylus fulvicephalus), as well as caddisflies and craneflies.

How lovely is this male White-jawed Yellow-face Bee (Hylaeua confusus) found at Ogmore Washeries, Bridgend, this week!?

This bee was one of two bees to be added to the former coal washery's ever-growing species list this week (the other bee was the Small-flecked Mining Bee, Andrena coitana).

Absolutely delighted to come across Bilberry Bumblebee (Bombus monticola) workers foraging on bird's-foot-trefoils at the former International Colliery, Blaengarw, this afternoon. We're so fortunate to have these beautiful bumblebees in the South Wales Valleys!

A few sightings from a quick visit to Darren Fawr Tip, Garw Valley, today: Dingy Skipper (Erynnis tages), Small Heath (Coenonympha pamphilus), Green Tiger Beetle (Cicindela campestris), and American Blue-eyed-grass (Sisyrinchium montanum). The latter appears to be doing well there.

Enjoyable day spent exploring tips in the Cynon Valley around Abernant and Cwmbach with friends. Tawny Mining Bee (Andrena fulva) seen foraging on Whinberry on one tip. A surprise find was the millipede Polydesmus barberii, which is endemic to southern Europe (along the French and Italian Rivieras).
