Light being shone to safeguard the future of sun loving critter

Nature-lovers are being urged to help shed light on a rare winter sun-loving insect.
The Northern February Red Stonefly (Brachyptera putata) was first found in the River Clyde in 1838 but now it mainly occurs in northern Scotland, particularly the strath and wider Highlands as well as north-east.
Outside of Scotland, it has only been found in two other rivers, the Usk in Wales and the Wye near Hereford, where it is now thought to be extinct.
This small, native, endemic stonefly is brown in colour. The female has three dark bands across its wings, as well as dark wing tips, whilst the male is short-winged and either cannot fly well or is unable to fly.
Adults have long antennae, a similar length to their bodies, which look like a (very small) string of beads.
The elusive insect is known to enjoy ‘basking’ on fenceposts along the river banks – and spotting them doing this has been identified as a useful survey technique.
Citizen Scientists have used this method to help identify adult Northern February Reds further afield on the River Dee at Balmoral and at the River Conon near Marybank.
Buglife Scotland is asking the public to help improve mapping of the rivers in which this stonefly lives and this is the perfect time of year to spot them.
They have said it is easy to get involved – simply take a picture of any potential stoneflies you come across and send it to scotland@buglife.org.uk or tweet it to @buglifescotland.
Craig Macadam, Buglife’s Conservation Director, said: “The Northern February Red is a really special species; we’re incredibly lucky to have it in some of our rivers.
"Now is the perfect time to spot them, particularly on fenceposts along riverbanks so look out for them as they bask in the winter sunshine.
“Stoneflies need clean, cold water which makes them important indicators of good water quality but climate change means that some species are under threat.
"By getting more people spotting stoneflies we can start to fill in the gaps in our understanding of where the Northern February Red stonefly lives, this will help with current and future work to help this species to survive.”
Understanding of the range and behaviour of the Northern February Red is already much improved thanks to volunteers sending in records during previous years.
But with more spotters – whether they are anglers or local residents along rivers – conservationists would be able to gain a better picture of their distribution and habits than ever before.
