This Caterpillar is an agricultural pest feeding on the foliage of many crops and garden flowers, including :
However, this species does not seem to develop resistance to insecticides like its cousin Helicoverpa armigera does.
The caterpillar is initially pale green, often with black dots and a pattern of thin dark lines running along the body.
In later instars , dark lines become less conspicuous. The caterpillar has a characteristic posture when disturbed: it lifts its head and curls it under the front of the body. If even more disturbed, it lets go and drops, rolling into a spiral.
When fully grown (4 cms.) it pupates in a cocoon under the soil. After about three weeks the adult emerges.
The adult moth has brown forewings with a delicate darker tracery. The hindwings are buff with a dark border.
Underneath, it has dark subterminal bands on each wing, and a black comma and a black dot on each forewing. The moth has a wingspan of about 4 cms. The chemical identities of the sex attractant compounds for this moth ( pheromones) have been elucidated.
The adult moths look very similar to those of the related species in the same genus : Helicoverpa armigera. However, for Helicoverpa punctigera
The moth migrates over large areas of the country, and is found, for example, in:
and has invaded
The migrations makes control difficult. Attempts to control the species include :
Note that Helicoverpa punctigera is a different species from Heliothis punctifera.
