Macronychus quadrituberculatus, which we've fondly nicknamed the Riverwood Riffle Beetle, has been recorded in Staffordshire for the first time in over 150 years.
This is a rare species in Europe. It is a flagship indicator species for healthy lowland river reaches. @coleopsoc.bsky.social

At just 3mm long the riverwood riffle beetle is BIG news for environmentalists in Staffordshire.
Why? Because it hasn't been recorded here for more than 150 years!
Our incredibly knowledgeable volunteer David Coles discovered on his moth trap sheet late one summer evening.

Pedicia rivosa...simply one of my favourite true flies and a good indicator of species-rich, boggy woodland up on the North York Moors. Fen Bog today. @dipteristsforum.bsky.social #pediciidae #hairyeyes

250-500 years ago, the freshwater white-clawed crayfish was recorded across much of England (although not Ireland). It is now steeply declining in Britain due to the introduction of the signal crayfish which carries crayfish plague. 🦞🤍 Map from my #AtlasOfEarlyModernWildlife #envhist #biodiversity

Absolutely crawling with #invasive #nonnative Signal Crayfish in Culford Stream including one (lower right) that seemed to be diseased. Note the diagnostic red under claw of this angry one, to separate it from the native White-clawed.
