Around the World in 26 Million Years : Diversification and Biogeography of Pantropical Grass-Yellow Eurema Butterflies (Pieridae: Coliadinae)
Aim: Grass-yellow butterflies (Eurema) are a group of pantropical Pieridae distributed throughout Asia, Australasia, Africa and the New World. However, little is known about their diversification, including the biogeographic mechanism(s) explaining their circumglobal distribution. We present the first densely sampled, time-calibrated phylogeny and biogeographic reconstruction of grass-yellows to c
