The paper develops an integrated framework combining isotope geolocation, ecological data, and atmospheric modeling to trace regional-scale pest insect dispersal, demonstrating long-distance dispersal of spruce budworm across 400 km.

The paper uses isotope geolocation and genome-wide analysis to show that short- and long-distance migratory V. cardui butterflies are genetically undifferentiated, suggesting migration distance is environmentally plastic.
