approx 1cm long, they were bright blue & hopped like a grasshopper (did not fly. There were c6 in small area of rough grassland near a path.
No interactions present.
They really were turquoise blue so believe they were female. Think I'll have to remember this as a 'green leafhopper' for now even though they were turquoise !
