Life Cycle of Tridrepana unispina
Egg The egg of tridrepana unispina is often laid on plants and represents the first stage of life. It's distinguishable by its small, oval shape and color, which can blend with the plant surface for camouflage.
Larva As a larva, tridrepana unispina exhibits rapid growth. This stage is designed for eating and growth. The larva can have striking patterns for defense, and it molts several times, increasing in size with each molt.
Pupal During this stage, tridrepana unispina is encased in a chrysalis. Inside, it undergoes a remarkable transformation, with tissues rearranging to form adult structures. The pupa remains static, attached to a substrate.
Adult Emerging from the pupa, the adult tridrepana unispina'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 and Where Can You Find Tridrepana unispina at Different Life Stages
Egg Tridrepana unispina eggs are typically laid on the underside of host plant leaves. To find them, closely inspect the foliage of known host plants for tiny, spherical or ovate objects that might be tridrepana unispina eggs.
Larva Tridrepana unispina caterpillars can be found on or near their host plants. Look for signs of feeding, such as chewed leaves, and search along the stems and both sides of leaves.
Pupal To find tridrepana unispina pupae, look for them attached to plant stems, leaves, or even in the leaf litter near the host plants. They may be camouflaged, so observe carefully.
Adult At night, use a light trap to attract tridrepana unispina as they are drawn to light sources. During the day, you may find resting tridrepana unispina with wings closed on tree trunks or camouflaged against branches of their host plants.
