The Caterpillars have sparse grey hairs, and are black with orange spots, and have broken cream lines along the body: a narrow line along each side, and broad line along the back. The caterpillars feed on various plants from BORAGINACEAE such as:
They grow to about 3 cms. The animal then pupates in a loose cocoon spun in the leaf litter on the ground below the foodplant.
The moth looks quite white when it is flying, but at rest, the pretty pattern of red and black spots on the white forewings can be seen. Each hindwing is white with two black spots and an irregular black margin. The moth has a wingspan up to about 3 cms.
The adult moth is superficially similar to Utetheisa lotrix, but there are subtle anatomical differences, and the pattern of pink and black spots is different. In particular, there are five red spots along the inner margin of each forewing (although the last two are sometimes joined). Also the males have a fold along the inner margin of each hindwing covered in hairs which appears to hold a pheromone.
The eggs are white and laid in a row or singly on a foodplant leaf.
The species occurs widely in the Indo-Australian region, including :
and much of Australia, including
Note that this is a different species from Utetheisa pulchella (Linnaeus, 1758), which occurs mainly in the northern hemisphere.
The correct genus name is Utetheisa; author Hubner (with an umlaut over the u), 1819. Sometimes it is listed as Utethesia, but this is a misspelling made by Moore in 1860.
