Furthermore, it is found in Japan and in Queensland and Northern Territory in Australia towards India and Sri Lanka.

[3] There are several generations per year, though development slows down in cooler seasons, when the larvae sometimes overwinter by boring into the bulbs of the host plants.

[4] The larvae feed on all species of Crinum, Clivia and Hippeastrum, including Crinum angustifolium, Haemanthus species, Hippeastrum procerum, Pancratium maritimum,[5] Zephyranthes candida, Crocus tommasinianus, Narcissus spp., and Amaryllis belladonna.

Commonly they bore into thick leaves or even into the bulbs; Mature larvae are likely to feed externally, especially on thin-leaved plants.

For small scale horticulture, or in home gardens it is better to rely on mechanical control, seeking out discoloured feeding patches on leaves and crushing the young larvae before they develop.
