How to Identify Asian comma?

Rectangle
Life Cycle of Asian comma
Egg The egg of asian comma is small, round, and often has a ribbed surface. Typically attached to foliage, the eggs are laid in groups and hatch within a few days to weeks, depending on temperature.
Larva Upon hatching, the larva of asian comma appears as a caterpillar. The caterpillar has a segmented body with a distinct pattern. It grows rapidly, molting several times, and its primary function is to eat and store energy.
Pupal After reaching a certain size, the caterpillar of asian comma forms a chrysalis for pupation. During this stage, it is immobile and undergoes a significant transformation. Its tissues are reorganized into the adult structure.
Adult The adult asian comma emerges with brightly colored wings, larger eyes, and a slender body. Its wing patterns serve for camouflage and mating. This final stage is for dispersal, feeding, and reproduction.

Habitat Preferences of Asian comma Through Different Life Stages
The eggs of asian comma are typically found on the underside of leaves from favored host plants. As larvae, they are found on or near their food sources – often on nettles, hops, or elm leaves – where they feed voraciously. Searching through these plants will likely reveal them. The pupae attach themselves to structures or plants, sometimes using silk, and can be discovered in sheltered areas such as under ledges or in crevices, often camouflaged by their chrysalis’s resemblance to a leaf. The adult asian comma butterflies are mostly located in temperate habitats including woodlands, orchards, and gardens where they can be seen basking in the sun on the ground or on leaves.
Rectangle
When is the Best Time to Observe Asian comma
The best time to find adult asian comma is on sunny days when temperatures are warm, as they are more active and easier to spot when basking or feeding on nectar.
Rectangle
What is the Best Weather to Observe Asian comma
Asian comma adults are more likely to be seen in non-windy, warm, and sunny conditions, as opposed to cold or rainy days, where they tend to hide.
Rectangle
How and Where Can You Find Asian comma at Different Life Stages
Egg Asian comma eggs are often laid on the underside of host plant leaves. Look for clusters of tiny, pale eggs on plants that asian comma caterpillars are known to feed on.
Larva Asian comma caterpillars can be found on host plants, where they feed on leaves. Search for nibbled leaves or frass (caterpillar droppings) as indicators of their presence.
Pupal Asian comma chrysalises are typically found in sheltered places near their host plants. They can be camouflaged, so look closely for their distinctive shapes attached to plant stems or leaves.
Adult Adult asian comma can be spotted feeding on nectar from flowers, basking in the sun, or sipping minerals from wet soil or puddles. Visit flowers, sunny open areas, or edges of water sources during warm parts of the day.
