🌱With the first signs of spring appearing, the Riverfly HQ team is already looking forward to warmer days back out sampling by the river.
☀️This sunny snapshot from summer 2025 has us excited for the season ahead!

🧪 Citizen science in action!
Peter Hanks from the West Cornwall ARMI Hub has built his own sorting table to make Riverfly monitoring easier in the field.

Under the surface of our rivers lives a hidden world of invertebrates - the tiny “riverflies” that keep ecosystems alive. Discover why monitoring and protecting their habitat matters and what a healthy river really looks like.

🪰 Freshwater Friday - Flat-bodied stone-clingers (Heptageniidae)
Larvae in this family of mayflies have a flattened shape, which is perfect for clinging to rocks in fast-flowing streams.
If you spot them, it’s a good sign of a healthy river.

🎥 Riverfly Quiz Time! 🐛
Can you guess this riverfly? 👀
Look closely... those tufted gills on the abdomen are a big clue!

Nicky from @gwksouth.bsky.social spent a Saturday morning at Willowbank in #NewDenham with Malcolm and his #volunteer friends recently and was impressed by their #Riverfly monitoring skills and set up, thank you Roger @goldcrest10.bsky.social for the photos. @riverflies.bsky.social
Riverfly data in action! 💧
At Stadhampton Mill, a new bypass channel has reconnected 3.25 km of chalk stream habitat. Early RMI scores are strong (10s) & stoneflies are back - rare for the catchment! 🐟🌱

Lara said ‘I’ve never had such a great #riverfly session. The riverfly were emerging in the tray and flying away’. Look at this one on the hat. Any perch will do!
Dedicated volunteers who go out #Riverfly surveying on the Colne at #Staines Moor in all conditions. A great fun session also enjoyed by Lara Clements Rivers Offer @gwksouth.bsky.social

These surveys give an idea of the quality of the water and alert us to changes or possible pollution events. Thank you to all of our dedicated volunteers.

Today Wear Rivers Trust held a Riverfly Training session, on the River Gaunless! 💧
We spent the day in the sunshine learning how to monitor river health by identifying freshwater invertebrates such as mayfly, Caddisfly and Stoneflies! 🪳

Today’s focus: the stonefly! 🪰 From nymph to adult, stoneflies play a crucial role in our river ecosystems.💧Sensitive to pollution, they help us to monitor water quality and assess the impact of environmental changes within the Wear Catchment! 🔍 #riverfly #invertebrate #rivers
On 5th March, Riverfly Partnership Development Manager Trine Bregstein delivered a webinar for the Catchment Based Approach (CaBA) about the latest developments in the Riverfly Partnership.

Really is a great way to help your local river #riverfly #riverchess
Old Carr Stream is rich in #riverfly larvae; Blue-winged Olive Mayfly (Serratella ignita, with Clausiliinae shell) and caddisflies: intricate towers of Limnephilus stigma, mosaics of Welshman's Button (Sericostoma personatum) & igloos of Little Black (Glossosomatidae) @riverflies.bsky.social 9/9
Amazing #Riverfly session in the sun on Saturday 1st March at Kingfisher Gardens #Iver
The first ever survey at this location, with new monitors, getting to know the ropes. Thanks to the new #volunteers and Lara from @GwkSouth for leading
@richings_park @riverflies.bsky.social
I post quite a lot about my local environment. I'm a #WaterGuardian with @dorsetwildlife.bsky.social , for whom I also monitor #Riverfly @riverflies.bsky.social . I also do CSI water sampling with Westcountry Rivers Trust. This is my local patch.

Here's some willow coppicing our volunteers created earlier this week on Skeeby Beck, a tributary of the River #Swale:
Our #Riverfly monitors have been busy in the last couple of months - a real variety of cased caddis at Hinderclay Fen. Thanks to all of them especially those that are wading in the cold water. Photos courtesy of Ellie Beach.
