Life Cycle of Black-waved flannel moth
Egg Upon laying, the egg of black-waved flannel moth appears small and spherical. The color and size may vary but generally are inconspicuous to avoid predation. The egg serves as the protection for the developing embryo until the larva is ready to emerge.
Larva The larval stage of black-waved flannel moth is characterized by its voracious appetite, feeding primarily on host plants. This stage sees significant growth, molting several times and dramatically increasing in size with a body consisting mainly of a digestive system.
Pupal During the pupal stage, black-waved flannel moth undergoes a transformative phase inside a cocoon. It ceases to feed and remains relatively immobile. This stage is marked by significant internal changes as tissues are reorganized into adult structures.
Adult Emerging from the pupa, the adult black-waved flannel moth’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 Black-waved flannel moth Through Different Life Stages
The eggs of black-waved flannel moth are typically found on the underside of leaves of host plants. As it progresses to the larval stage, black-waved flannel moth caterpillars can be discovered on the leaves or bark of trees, often in regions with dense foliage where they can feed and are somewhat protected from predators. Searching for these hairy caterpillars might require careful examination of leaves for feeding signs. The pupae are often harder to find, as they cocoon in secluded places such as crevices or under loose bark. To find black-waved flannel moth in its adult moth stage, the search should be concentrated near the habitat of the caterpillars often around areas with ample nectar sources such as flowering plants during nighttime as they are nocturnal.

Toxic to Humans

Black-waved flannel moth is a caterpillar whose hair contains neurotoxins that can cause a range of effects on humans, from mild irritation to severe pain. When touched, their hair releases the toxins, which can lead to symptoms such as headaches, fever, muscle spasms, and difficulty breathing. In some cases, the reaction can be significant, necessitating medical attention.
