A New Butterfly with Zac MacDonald and Julian Dupuis

A butterfly sits on a yellow flower. It is tan in color with a large abdomen and long, thin antennae. It has big black eyes. It is adorable.

Think butterfly genomics is a simple topic? Think again, but this time think alongside Zac MacDonald and Julian Dupuis. Not only are they answering some of the most interesting contemporary conservation questions, but they’re doing so using a very curious butterfly as their model organism. “One of the difficult things with studying these kinds of butterflies….is we don't really understand fitness or adaptive value as well as we do in cougars or in foxes or in dogs or in other vertebrates that we've studied a lot more.” Julian says. “We don't really have these characteristic signals of, what does inbreeding depression look like? We just don't have that kind of information in butterflies.”

Listen in to learn about cutting edge genomics from certified self-described “crazy butterfly people” and expand your idea of what is possible in conservation.

Zac and Julian’s paper “Genomic and ecological divergence support recognition of a new species of endangered Satyrium butterfly (Lepidoptera, Lycaenidae)” is in volume 1234 of Zookeys.
