Life Cycle of Black-spot chestnut
Egg An embryonic stage where the black-spot chestnut begins life as an egg. Size is tiny, color can vary; often matches the host plant.
Larva In this stage, the black-spot chestnut exhibits significant growth. It's a worm-like caterpillar with a distinct color pattern meant for feeding and growth.
Pupal Transformation occurs inside a chrysalis; the black-spot chestnut is inactive externally, but major internal changes happen as tissues are rearranged.
Adult The adult black-spot chestnut emerges with wings and reproductive organs. Distinguishable by its color and patterns on the wings, it focuses on mating and laying eggs.

How and Where Can You Find Black-spot chestnut at Different Life Stages
Egg Eggs of black-spot chestnut are typically laid on host plants. Locate them by carefully examining the leaves and stems of potential host plants for small, spherical or ovular eggs that may be laid in clusters.
Larva Black-spot chestnut larvae or caterpillars can be found on or near their food sources, which are the leaves of various plants. Look for signs of feeding such as holes in leaves, and search both the tops and bottoms of leaves for camouflaged larvae.
Pupal To find black-spot chestnut pupae, search the ground beneath host plants for buried pupae, or check the plants for pupae attached to leaves or in hidden places like curled leaves or beneath bark.
Adult Black-spot chestnut adults are attracted to light, so setting up a light trap after sunset can effectively lure them for observation. Alternatively, placing bait such as sugar or fruit-based bait in the area can also attract these adult moths.
