Who doesn’t love a good butterfly? Certainly Andy Warren loves these fluttering insects. This species was discovered in a fairly likely place: a museum collection. Museum collections are wonderful archives, that give us an in-depth look at diversity of a group, or region. In this case, Dr Warren noticed that some individuals of the species O. chryxus looked a little different. The outside of their wings were lighter in colour appearing almost ‘frosted’.
Through some careful taxonomy work, and genetic sequencing – Dr. Warren and his colleagues found that the frosted looking butterflies were a new species to science. This is the first butterfly that is endemic to Alaska, meaning it is not known from outside the state.
