Life Cycle of Robinson'S Underwing
Egg The robinson'S Underwing begins as an egg, which is often round or oval and minuscule. The color usually camouflages with the environment. The embryonic robinson'S Underwing develops inside until it's ready to hatch.
Larva Upon hatching, the robinson'S Underwing enters its larval stage. This caterpillar form is elongated, with a distinctive color pattern. It grows rapidly, molting several times as it increases in size.
Pupal After the final molt, the larval robinson'S Underwing forms a pupa. This immobile stage is a hard case, within which the robinson'S Underwing undergoes a remarkable transformation as its tissues are reorganized.
Adult Emerging from the pupa, the adult robinson'S Underwing'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.

Habitat Preferences of Robinson'S Underwing Through Different Life Stages
The eggs of robinson'S Underwing can typically be found on the underside of host tree leaves. Caterpillars, once hatched, reside on the host trees where they consume leaves and can often be spotted by examining the foliage. Pupae tend to be located in leaf litter or just below the soil surface at the base of the host trees. Adults, being nocturnal, are usually seen resting on tree trunks during the day or around lights at night. To search for these stages, inspect host tree leaves for eggs, carefully look through foliage for caterpillars, sift through leaf litter for pupae, and check tree trunks and nearby light sources after dark for adults.
