The Tailed Emperor (Polyura sempronius sempronius) is, for some reason, an uncommon visitor to the higher altitudes of the Ranges, though they are seen at lower altitudes. This specimen was found as a larva near Euroa, then ‘brought up’ by Ben at home in Boho South.
They’re a large butterfly, up to 55 mm wingspan and regarded as common in northern and eastern Australia in a wide range of habitats. In our region food plants include Acacias and Kurrajongs. This is the first specimen I’ve knowingly seen. The sexes are similar, but this specimen appears to be a male.
