This Caterpillar is long and green, with yellowish bands between segments. It is missing one pair of prolegs, so it moves like a looper, although not related to the true loopers in GEOMETRIDAE.

The caterpillar is often found in gardens on:

  • Musk Ockra ( Abelmoschus moschatus ), and
  • Hibiscus ( Hibiscus rosa-sinensis ),

    and is an agricultural pest on :

  • Kenaf ( Hibiscus cannabinus ), and
  • Cotton ( Gossypium hirsutum ),

    all of MALVACEAE.

    The caterpillars are inclinesd to lie along a vein on the underside of a leaf. The caterpillars damage the leaves of their foodplant in a characteristic pattern.

    typical pattern of damage to Hibiscus leaf by Anomis flava caterpillars

    Old Chinese drawings of Hibiscus show damage to the leaves that is similar in pattern to this which we observed on the bushes in Sydney (Anomis flava is found in China). The caterpillar grows to a length of about 4 cms.
