Dr Martian Warren from Butterfly conservation said:Scotland is on the brink of an airborne invasion by a conucopia of foreign butterflies
Among the anticipated first time visitors is the grenanium bronze, a small dark-brown butterfly more commonly found around the mediterranian.
"For example, the mountain ringlet found at high altitude, could be thretened by climate change. There is evidence it's incresingly retreating up mountains in search of cooler climates. The worry is that they're pushed so high they'll lose their habitat completly."
