This Caterpillar is yellow, with rows of black spots containing white dots along its length, and a red spot on each of the penultimate two segments. Each black spot has a bunch of hairs sticking out from it. A pair of black hair pencils stand out near the head like a pair of horns. The caterpillar has been found on :

  • Cultivated Grape Vine ( Vitis vinifera, VITACEAE ),

    On the grapes, they feed on the stems of the bunches of fruit, seemingly only eating the fruit as a last resort.

    Pupation occurs in a pale brown cocoon spun in its bunch of fruit.

    The adult moths have white wings, with the males having a brown leading edge to the forewings. The abdomen is deep yellow, and hairy. The thorax is brown. The moths have prominent black eyes, and both sexes have feathery antennae. The moths have a wingspan of about 2 cms.
