hello friends of steemit I found this beautiful caterpillar yesterday and it caught my attention to know its description and its family since it is a very rare species and had not seen it before and wanted to know its origin, for its dragon head and its horns which is what what more calls attention in it.
Polyura (pyrrhus) sempronius, the tailed emperor, is a large butterfly by Australian standards, with a wingspan of some 75 mm for males and 85 mm for females. The uncommon but widespread[2] butterfly occurs in a variety of habitat types in northern and eastern Australia, where it occurs predominantly in the warm and subtropical coastal regions. It is a resident species where its food plants, certain legumes (Mimosaceae and Caesalpiniaceae) and kurrajongs, are native.
Larva
The green, mature caterpillar is unique among Australian butterflies. A yellow line runs along each side, and the back is marked by one or more crescent shapes. The green head has two pairs of long horns besides a smaller set behind the head-scale.
Adult
The upperside is boldly marked in black and white, with narrow blue-grey margins, and specks of orange on the hindwings. The prominent double-pointed tails gives the butterfly its name. The underwing of both sexes are marked in complex patterns of red and yellow brown, against on a white background, bordered by black outlines and an orange edge to the hindwing.
