The Caterpillar of this species has broad stripes of varying shades of dark green to dark brown, separated by fine white lines, and has a broad pale stripe along each side. The caterpillar has pale hairs behind the head, which distinguish it from similar species. The caterpillar is an agricultural pest on many crops, including :
as well as feeding on other plants from the families:
but curiously, will not attack:
The adult moths have brown forewings, sometimes with a bold distinctive pattern, and sometimes just brown crossed by some irregular thin black lines.
The hindwings are brown fading to white at the base.
The undersides show a large dark comma-shaped mark under each forewing. The moths have a wingspan of about 3 cms.
The moths can occur in huge numbers, and migrate from one part of the country to another. In November 2005, the moths caused a panic at Murray Downs Golf Club. Swarms of the moths invaded the course, and the clubhouse was totally inundated for 24 hours or so by the moths. They were an absolute plague. The walls, ceiling and floor of the clubhouse was quite literally covered with resting moths. The clubhouse had to be closed for a while to eradicate them. The air on the course was also "thick" with them at the time. They were a 24 hour wonder. They had gone within a day.
The species occurs throughout most of Australia, including
Note that this is a different species from Helicoverpa punctigera.
