Larva Purple thorn caterpillars can be found on host plants where they feed. Look for signs of feeding, like chewed leaves, and inspect both sides of the leaves for the presence of caterpillars.
Pupal Purple thorn pupae are often hidden in sheltered spots such as under leaves, on plant stems, or within the leaf litter. Carefully searching these areas can reveal the well-camouflaged pupae.
Adult Purple thorn adults can be found near light sources at night or resting on the bark of trees or shrubs during the day. They may also be spotted seeking nectar on flowering plants around dusk.
