Global invasion history of the agricultural pest butterfly Pieris rapae: a citizen science population genomics study

Here we demonstrate the power of the public to aid in collections-based research, where through an international citizen science project, Pieris Project, we were able to generate genetic evidence and combine it with historical records to uncover routes of invasion of the small cabbage white butterfly—Pieris rapae. We find that the spread of this butterfly across Eurasia occurred relatively recently (
