Life Cycle of Biston regalis
Egg A tiny ovum, the egg of biston regalis is often laid on plant surfaces. Depending on species, eggs can vary in color and shape, usually camouflaged and fixed securely to prevent displacement.
Larva The caterpillar, or larva, of biston regalis hatches with a primary focus of feeding and growth. It molts several times, progressively increasing in size and sometimes changing patterns for better camouflage.
Pupal Encased within a hardened chrysalis, biston regalis undergoes drastic transformation. The pupal stage is a resting phase with internal reorganization, leading to the adult form. The pupa may show color variations with season or surroundings.
Adult Emerging from the pupa, the adult biston regalis’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 Biston regalis
To attract biston regalis, one might use light traps since they are nocturnal and are commonly attracted to sources of light at night.
Rectangle
Habitat Preferences of Biston regalis Through Different Life Stages
The larval stage of biston regalis can generally be found on the leaves of the host plants, where they feed and grow. Searching for larval biston regalis requires examining the undersides of leaves for caterpillars that blend in with the foliage. The pupal stage typically occurs in a sheltered spot among leaf litter on the ground, where biston regalis cocoon can be found attached to twigs or bark. To locate pupae, it's necessary to gently sift through the litter or inspect the crevices of tree bark. Adult biston regalis are commonly encountered on tree trunks or resting on foliage, and they are best searched for at night when they are active and attracted to light sources.

How and Where Can You Find Biston regalis at Different Life Stages
Egg Biston regalis eggs are often laid on host plants. To find them, inspect the leaves, stems, and even the underside of leaves of suspected host plants for small, spherical or oval-shaped eggs.
Larva Biston regalis larvae are caterpillars that can be located by looking for signs of feeding damage on host plants, such as chewed leaves. They can often be found on or near their food sources during the day.
Pupal Biston regalis pupae may be found in areas of vegetation where the larvae feed, often camouflaged or hidden in the underbrush, in leaf litter, or attached to twigs or leaves.
Adult Biston regalis adults can be lured in with light traps at night, as they are attracted to bright lights and can thus be observed or captured for study.

Forestry Pest

Larvae of biston regalis feed on the leaves of broad-leaved trees, which can result in defoliation ranging from mild to severe. Low populations may only cause minimal damage, but high densities can lead to significant defoliation, weakening trees and potentially leading to their death. This can have downstream effects on forest ecosystems and associated industries.

Rectangle
Hurt Plant

When biston regalis larva feeds, it chews through the plant tissues of oak and hornbeam, primarily damaging leaves and fruits. This feeding results in defoliation and scarred fruit surfaces, which can stunt growth, diminish photosynthesis, and lead to potential crop losses. The insect's voracious appetite affects the plant's overall health and productivity.
