How and Where Can You Find Residua Underwing at Different Life Stages
Egg Residua Underwing eggs are usually laid on the underside of host plant leaves. To find them, inspect the host plants closely, particularly looking under the leaves for small, round or oval eggs.
Larva Residua Underwing larvae or caterpillars can be found on or near their food plants. Search by carefully examining the leaves for chewing damage or frass (caterpillar droppings), which indicates their presence.
Pupal Residua Underwing pupates in secluded places such as under the bark of trees or in leaf litter. To find residua Underwing pupae, gently sift through leaf litter or investigate crevices in tree bark.
Adult Adult residua Underwing moths are attracted to light, so setting up a light trap at night can be an effective method. Alternatively, a bait consisting of a sweet mixture can be painted on tree trunks or poles to attract and observe them.
