Scarce Yellow Sally Stonefly
Isogenus nubecula
Isogenus nubecula, also known as scarce yellow sally, is a species of stonefly belonging to the family Perlodidae. It is native to Europe.
The insect was thought to be extinct in Britain, having last been recorded in 1995, but a small population was found on the River Dee, Wales in 2017. In 2023, the insects were being bred in captivity at Chester Zoo with a view to reintroduction to the wild when water quality has improved.
