How and Where Can You Find One-eyed sphinx at Different Life Stages
Egg One-eyed sphinx eggs are often laid on host plants. To find them, inspect the leaves of known host plant species for small, spherical or ovoid objects often found on the underside of leaves.
Larva One-eyed sphinx larvae, or caterpillars, can be found by searching the foliage of host plants. These caterpillars are usually larger and may have distinct markings or coloration that can help identify them.
Pupal One-eyed sphinx pupae may be concealed in the soil, leaf litter, or among plant matter near the host plant. Carefully sift through potential hiding places to locate the camouflaged pupa.
Adult One-eyed sphinx adults can be found by using light traps at night or by setting out bait stations with sweet liquids. Keep an eye out for these creatures near flowers or sources of light after dusk.

The mournful sphinx (Enyo lugubris) most likely gets its name from the somber colors that make us think of a desert environment, with deep, dark browns. Other people think that it may be related to its droopy posture, but this is just speculation. The insect is also attracted to lights, meaning it flies and is difficult to spot during the nighttime.
