I am excited to tell you about our new study led by Tyler Audet and in collaboration with Stefan Lüpold's group. Below you see two species. On the right is Drosophila melanogaster. On the left, Drosophila prolongata. Notice the highly exaggerated legs of the males in D.p! doi.org/10.1093/evol...
Two panel image of Drosophila prolongata and Drosophila melanogaster. In the top panel is a female of Drosophila prolongata on the left and a female of Drosophila melanogaster on the right. It shows that D. prolongata females are somewhat larger than melanogaster, and have spotted wings. Importantly the legs are proportional in each species.

In the bottom panel are males. On the left is a Drosophila prolongata male which is larger than all the other individuals, and has highly exaggerated legs in terms of width and length, and also has black stripes. In contrast male Drosophila melanogaster are much smaller than all the others, with normally proportioned legs.
