Description, Biology, Life Cycle, Damage, Common Names, Images

- Adult: 35 mm wingspan. Reddish black fore wings, darker marginally, each bearing a yellowish spot circled in black; light beige hind wings.
- Larva: 45-50 mm long. The body is dark brown with lateral black spots as well as a whitish double line on the sides.

- Host plants: wild plants in fields of cereals then the neighbouring cultivated plants: cabbage, potato, beans, onions, red beet, etc., also vine.
- Adult: sedentary.
- Larva: feeds at night and hides in the ground during the day. The young caterpillars first feed on wild plants then, having reached the penultimate instar, they invade neighbouring crops.
- Pupa: the caterpillar forms a pupa in the ground; pupal stage lasts 40 days.

[R]Life Cycle
- 1 generation per year.
- The moths fly in July; the eggs laid at that time remain in diapause and hatch at the end of winter.

The larvae cause serious losses around end of April- beginning of May when they invade seedling crops and young shoots which are extremely vulnerable. They can also climb vine stock and destroy the buds.
