Yellow Shell

Yellow Shell

Camptogramma bilineata

A species of Camptogramma

The striking yellow Shell is known for its impressive ability to blend into its surroundings, thanks to its vibrantly patterned wings, which mimic the detailed textures of local flora. Especially adept at evading predators during its larval stage, where it resembles a twig, this species undergoes a remarkable transformation into an adult that feeds primarily on nectar, contributing to local ecosystem pollination.

Life Cycle of Yellow Shell
Egg Upon oviposition, the egg of yellow Shell enters the life cycle. The egg's shape, size, and color may vary, generally being small, round, and subtly colored to blend into the environment, reducing predation risks.
Larva As a larva, yellow Shell primarily focuses on eating and growing. It has a segmented body with a well-developed head and mouthparts for feeding. The larva molts several times, increasing in size and sometimes changing colors or patterns.
Pupal In the pupal stage, yellow Shell undergoes drastic transformation within a protective casing. Metamorphosis radically alters its internal and external structure. The pupa is immobile, and the colors often mimic the surroundings for camouflage.
Adult Emerging from the pupa, the adult yellow Shell’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 Yellow Shell
Light traps and pheromone traps are effective for attracting adult yellow Shell, as they are nocturnal and are drawn to light or the scent emitted by the pheromones.
Rectangle
Habitat Preferences of Yellow Shell Through Different Life Stages
The eggs of yellow Shell are typically found on the underside of leaves of its host plants, which include a wide variety of herbaceous species. Caterpillars, after hatching, can be seen on the leaves or stems of the plants, camouflaging with their surroundings. When searching for pupae, inspection should be centered around the base of plants or in the leaf litter, as they tend to pupate in secluded areas on or near the ground. Adult yellow Shell are usually nocturnal and can be found resting on tree trunks or foliage during the day, or they can be attracted at night using lights or sugar baits.
Rectangle
When is the Best Time to Observe Yellow Shell
The best time to find yellow Shell is at dusk or during the night for adults, while larvae are most active during the day, especially in warm weather.
Rectangle
How and Where Can You Find Yellow Shell at Different Life Stages
Egg Yellow Shell eggs are typically laid on the host plants. Search for small, round or oval eggs on the underside of leaves of known host plants.
Larva Yellow Shell larvae can often be found on the host plants. Look for caterpillars feeding on leaves, and search around areas with signs of leaf damage or frass (caterpillar droppings).
Pupal Yellow Shell pupae might be found attached to twigs or leaves, or in leaf litter on the ground. Carefully inspect potential pupation sites on or near the host plants.
Adult Yellow Shell adults can be lured using light traps at night. They can also be found resting on the bark of trees or under leaves during the day.

Agricultural Pests

When 'N' larvae infest crops, they chew on leaves, potentially causing mild to severe damage. A few larvae may lead to spot defoliation, while a large infestation can devastate entire plants, impacting yields. This pest’s activity can harm humans by reducing the availability and increasing the cost of affected crops like beans and lettuce.
