On a more personal note, this paper is the final chapter of my thesis to be published. I’m super happy to have all four chapters out within a year of defending! #PhDone

Thank you again to my wonderful coauthors without whom this project would have been impossible: Daria Shipilina, Venkat Talla, Farid Bahleman, Khadim Kébé, Johanna Berger, Niclas Backström, Gerard Talavera, and Clément Bataille

So why do some painted ladies migrate across the Sahara while others don’t? Only future studies will be able to tell us for sure, but for now, we hypothesize that migration distance in painted ladies is a plastic response to environmental conditions, such as photoperiod

Geometric morphometric analysis, accomplished by Johanna Berger and I, ultimately showing that the differences in migration distance could not be explained by wing size, wing shape, sex, or wing wear score

We performed whole-genome resequencing on our painted ladies. My co-lead author, Daria Shipilina, led the genomic analysis, with input from Venkat Talla, Niclas Backström, Gerard Talavera, and me. We found no genetic differentiation or population structure associated with migration distance

By applying hydrogen and strontium isotope geolocation, Clement Bataille and I confirmed distinct differences in migration distance – butterflies flew either long distances to sub-Saharan Africa – one over 4,000 km! - or short distances to the Mediterranean

First, Farid Bahleman and Khadim Kébé collected painted ladies south of the Sahara in the autumn. At the same time, Gerard Talavera and I collected painted ladies from the circum-Mediterranean region
