Habitat Preferences of Mourning Underwing Through Different Life Stages
The eggs of mourning Underwing are typically found on the leaves or bark of host trees, especially poplars and willows. The larvae, or caterpillars, live and feed on the foliage of these trees, often camouflaged well to avoid predators. As they enter pupation, mourning Underwing larvae seek out loose bark or leaf litter on the ground to form their cocoons. An observer attempting to locate mourning Underwing in its different stages would inspect the undersides of leaves and crevices in tree bark for eggs and caterpillars, while sifting through leaf litter and detritus near the host trees could reveal the pupae.

When is the Best Time to Observe Mourning Underwing
The suitable time to find mourning Underwing varies with its life stages and habits. Adults of nocturnal lepidopterans are best found at night. The caterpillar stage might be more active during the day and easier to find when they are feeding on host plants.
Rectangle
What is the Best Weather to Observe Mourning Underwing
Calm, warm nights are often ideal for attracting adult moths using light traps. Dry conditions are typically best for finding caterpillars, as wet weather may prompt them to hide deeper within foliage or in the ground.

How and Where Can You Find Mourning Underwing at Different Life Stages
Egg Mourning Underwing eggs are usually laid on the underside of leaves of host plants. To find them, inspect the leaves of known host species for small clusters or rows of eggs.
Larva Mourning Underwing larvae, or caterpillars, can be found on or near host plants. Look for signs of feeding, such as chewed leaves or frass (caterpillar droppings), and carefully check the plants to locate them.
Pupal Mourning Underwing pupae may be found in leaf litter, soil, or other sheltered places near the host plants. Gently sifting through potential pupating sites during the right season can reveal the pupae.
Adult Adult mourning Underwing are often nocturnal and attracted to lights, so setting up a light trap during warm nights could be an effective way to find them. Alternatively, one can search around the flowers or plants that adult mourning Underwing may visit to feed on nectar during dusk or dawn.
