The agricultural pest, silver Y moth ( Autographa gamma ), migrates to northern latitudes every summer to exploit available resources and to reproduce. Stable hydrogen isotope analysis localises the origins of Finnish spring migrants to central Europe, clearly separating them from the northern, locally emerging, autumn generation. Historical museum collections and current samples suggest that the emerging area of the spring migrants may have shifted towards the north during the last century, potentially with changing climate.
