Save Our Swale Exhibition in Catterick Library in collaboration with CRACCL until 22nd June.. What Does The River Swale Mean To Us All? #richmondsnippets

This olive, found by Warwickshire Wildlife Trust volunteers, is so pale because it's recently moulted. Riverfly larvae undergo a number of moults as they grow. Each stage between moults is called an 'instar'. At the start of an instar, before the exoskeleton hardens, the larva is pale and soft. 🌟

Nice to see BBC News shining a light on Buglife's Riverfly monitoring in Scotland! www.bbc.co.uk/news/article...

One measure of the #RiverVer health is the abundance of invertebrates living in the river. Every month a dedicated team of 20 volunteers survey nearly 20 spots along the Ver to check that all is well. @chilternstreams.bsky.social @riverflies.bsky.social

“We’re creating a mosaic of habitats – jewels linked by long watercourses. It’s a nature-based recovery; we’re just prompting it.” If you, too, feel that positive stories are in short supply, this tale about people coming together might just brighten your day. www.theguardian.com/environment/...

The RPHQ team will be in attendance - particularly looking forward to the riverfly-related talks!

Hundreds of our Riverfly monitors were originally trained by Stuart Crofts. He's long been a fantastic champion of the Riverfly Partnership, and this is a lovely interview with him by the FBA.

I’m now a qualified river fly monitor! Will be making regular checks on a local stream to identify and count the little critters that live there in order to better understand and counter pollution. Run by @riverflies.bsky.social best day I’ve had in yonks 😍

Our host organisation, @freshwaterbio.bsky.social, has its Annual Scientific Meeting on Thursday 11 June at Edinburgh Napier University. This year’s theme will cover a range of new approaches being used for freshwater science. Buy your tickets at www.fba.org.uk/shop/p/annual-scientific-meeting-2026

It was fantastic to see the Chilterns Chalk Stream hub demonstrating Riverfly monitoring on Countryfile at the weekend! You can catch the episode on iPlayer here: www.bbc.co.uk/iplayer/epis...

Love the slow-motion videos of dancing mayflies in this.

We invite you to take a cool freshwater plunge this Monitoring Monday... as we rejoice in rivers & the Realm of the Riverfly! Interested in becoming a guardian of your local #river as a citizen scientist #riverfly monitor? Find out more on the Riverfly Partnership website: www.riverflies.org

Fantastic start to the @riverflies.bsky.social sampling season at Hall Beck on the river Kent. Lots of lively larvae of #stoneflies, #mayflies and #caddisflies, including our first #Ephemera at this site. #citizenscience #freshwater

A great find!

Our Riverfly volunteers this weekend got a little local help from a pair of Mandarin Ducks (Aix galericulata) who paddled past the session. At these monthly sessions, counting the number of certain invertebrates gives us valuable information about the health of Beverley Brook @riverflies.bsky.social

Did you catch the first episode of Secret Garden on the BBC over the Easter weekend? There was a lovely segment about mayflies about halfway through - well worth a watch! www.bbc.co.uk/iplayer/epis...

Today we're celebrating Riverfly Monitoring Monday! Monitoring is an excellent way to protect #river health by supporting local community engagement, #citizenscience collaboration & sustainability for our #freshwaterecosystems. Please visit @riverflies.bsky.social for more info: www.riverflies.org
