Leucinodes orbonalis

Its native distribution is in the tropical and subtropical parts of Australia and Asia, where it is recorded from Pakistan, Nepal, India, including the Andaman Islands, Sri Lanka, Bangladesh, Myanmar, Laos, Cambodia, Vietnam, Thailand, China, Taiwan, Japan, Malaysia, Singapore, Brunei, the Philippines, and Indonesia (Java).

The central dorsum has a prominent orange to dark brown L-shaped or triangular spot leading to the forewing centre and often meeting with the distal discoidal stigma.

[1] The primary larval hostplant is eggplant or brinjal, Solanum melongena, where most of the economical impact of this species is reported.

[3] Eggs are laid during the night on the lower surface of the young leaves, green stems, flower buds, or calyces of the fruits.

Within an hour of hatching, the caterpillar (larva) bores into the nearest tender shoot, flower, or fruit.

The damaged shoots ultimately drop off, disturbing plant growth and reducing fruit number and size.

[6][7][8][9] Partners of the CABI-led programme Plantwise suggest synchronous planting with neighbouring fields to help reduce the spread of infestation.

[4][6][8][9][10] In small plantings, partners of Plantwise suggest infected shoots and fruits can be hand picked and eggs and larvae can be physically removed.

[6][7][8][9][11][13] Due to variable regulations around (de-)registration of pesticides, specific chemical control methods may differ between countries.
