Life Cycle of Double line
Egg The eggs of double line are laid in clusters and are typically oval-shaped. Initially, they're pale and then darken as embryonic development progresses. This stage is static, with the primary function being protection and development of the future larva.
Larva Upon hatching, the larva of double line is worm-like, with a tubular body and chewing mouthparts. It's focused on feeding and growth, molting several times. During molts, it increases in size, changes colors, and may develop patterns for camouflage.
Pupal The larva of double line transforms into a pupa, encapsulated in a chrysalis, which may be attached to foliage or buried underground. The pupa is immobile and experiences significant internal reorganization, developing adult structures.
Adult Emerging from the pupa, the adult double line’s development is marked by the presence of wings and functional reproductive organs. The body is fully formed and hardened, and the adult is mobile, focusing on reproduction.

How Can You Attract Double line
For the adult double line, light traps or pheromone traps are commonly used, as they are attracted to light at night or specific chemical scents emitted by females for mating purposes. Caterpillars of double line could be attracted to their host plant species where they feed.

What is the Best Weather to Observe Double line
Calm, warm, and humid nights are ideal to find adult double line as they are more active in such conditions. Caterpillars can be found when it’s not too hot to avoid desiccation and they are not hiding from the heat.

How and Where Can You Find Double line at Different Life Stages
Egg Eggs of double line are often laid on the underside of leaves or in hidden spots on host plants. To find them, inspect potential host plants in the habitat, paying close attention to the undersides of leaves.
Larva Caterpillars of double line can be found on or near the food plants they consume. Look for holes in leaves or feeding trails, and inspect both sides of leaves and stems for any camouflaged individuals.
Pupal Double line pupae may be in the soil, amongst leaf litter or on vegetation. Search around the base of host plants and gently sift through leaves or soil to locate them. Be careful not to disturb or damage any found.
Adult Double line adults are typically nocturnal. They are drawn to light sources, so setting up a light trap or using a flashlight to spot them as they fly or rest on nearby surfaces at night can be successful methods.

Hurt Plant

Double line damages Poaceae by feeding on their tissues. The insect chews through leaves and stems, impairing the plant's ability to photosynthesize and transport nutrients. This can lead to weakened growth, reduced vigor, and in severe cases, could contribute to plant death.

Attract Plant Feature
Color, Smell
Double line is a nocturnal pollinator, using its well-adapted sense of smell to locate flowers under dim conditions. Attracted to them by specific colors and scents, it may be inadvertently dusted with pollen while feeding on the flower's nectar, thus contributing to cross-pollination.
