Common Name(s)

  • teak defoliator

Scientific Name

  • Order: Lepidoptera (moths and butterflies)
    • Family: Hyblaeidae
      • Species: Hyblaea puera

Host(s)

Biology

Caterpillars of this species are brown with a pair of narrow yellow lines along each side enclosing a dark brown band. Eggs are laid on the undersides of the leaves. The caterpillar cuts a semicircular piece of leaf and folds or rolls it over to form a shelter. The mature caterpillar often lives in this shelter by day, and feeds nocturnally. The adult moth has a wing span of about 4 cms. It is brown with a yellow arc or series of blotches on each hind wing.

Control

Defoliation caused by teak defoliator larvae may be prevented by weekly applications of microbial insecticides containing Bacillus thuringiensis kurstaki such as Dipel®. These insecticides only kill feeding caterpillars and do not harm other organisms.
