Achemon sphinx

Achemon sphinx

Eumorpha achemon

A species of Eumorpha, Also known as Grape sphinx moth

The achemon sphinx (Eumorpha achemon) is a pinkish-brown moth that can be found in woods, shrubbery, and gardens. The caterpillars feed on grapes and ampelopsis, but the adult moths only eat nectar. The females lay their eggs on surfaces of old leaves, and when they hatch, the caterpillars burrow into the soil.

Appearance of Achemon sphinx
The wingspan is 9 - 10 cm. It can be distinguished from all other Eumorpha species by the hindwing upperside being almost uniformly pale pink from the base to the diffuse, dark brown submarginal band. Larvae are of three forms: light green, reddish orange, and tan to brown.

How to Identify Achemon sphinx?

Life Cycle of Achemon sphinx
Egg The eggs of achemon sphinx are laid on host plants and are often very small and inconspicuous. The color may blend with the plant to avoid predation. This stage is solely for the development of the embryo, which grows inside the egg until it's ready to hatch.
Larva Upon hatching, the larva of achemon sphinx immediately starts to feed on the host plant. This stage sees rapid growth, with several molts as it outgrows its skin. The larva is markedly different in appearance from the adult, being worm-like and often brightly colored for warning or camouflage.
Pupal The larva of achemon sphinx forms a cocoon or chrysalis during the pupal stage. This is a transitional phase where it undergoes significant transformation. The pupa may be attached to a structure or buried in soil. It's immobile and vulnerable, but protected by the hard chrysalis casing.
Adult Emerging from the pupa, the adult achemon sphinx's development is marked by distinct adult features including wings and functional reproductive organs. Colors often shift to patterns suited for mate attraction or further camouflage. The adult is fully mobile, engaging in feeding, mating, and for some species, migratory behaviors.

How Can You Attract Achemon sphinx
Adult achemon sphinx are particularly attracted to flowers with a strong fragrance, especially those that bloom at dusk, since achemon sphinx are typically nocturnal feeders. This includes flowers like petunias, honeysuckles, and evening primroses.
Rectangle
Habitat Preferences of Achemon sphinx Through Different Life Stages
Achemon sphinx larvae, commonly found on grapevine leaves in vineyards or gardens, are best searched for by examining the undersides of leaves for signs of feeding or frass. As they mature, they pupate in the soil, hence one should search for them by gently digging around the base of host plants. Adult achemon sphinx are typically nocturnal and attracted to light, so to locate them, one might set up a light trap in an area with abundant floral resources, such as near flowering plants, during the night.
Rectangle
How and Where Can You Find Achemon sphinx at Different Life Stages
Egg Achemon sphinx eggs are typically laid on the undersides of host plant leaves. Locating these eggs requires careful inspection of potential host plants, which for achemon sphinx can include grape vines or Virginia creeper.
Larva Caterpillars of achemon sphinx can be found on host plants, where they feed on leaves. Searching the leaves and stems of known host plants, especially where leaves have been chewed, is a good way to spot them.
Pupal Achemon sphinx pupate in the soil or leaf litter near the host plants. To find pupae, one can look for disturbed soil or areas with loose soil and leaf debris close to the host plant without disturbing the environment too much.
Adult To find adult achemon sphinx, one can set up a light trap with a bright light source to attract them at night or hand search by inspecting flowers that bloom at night, as they are nectar feeders and are attracted to the fragrance and flowering patterns of these plants.

Agricultural Pests

Larvae of achemon sphinx can cause mild to severe defoliation in grapevines, often starting on the softer, more succulent parts of leaves. Small populations may only result in cosmetic damage, while large infestations might lead to significant leaf loss, impacting photosynthesis and vine vigor, potentially reducing yield and fruit quality. The secondary effects can include a reduction in grape production and quality, which might influence wine industries, affecting local economies and labor.

Mournful sphinx

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.

Tetrio sphinx

The distinct larva of tetrio sphinx is recognizable by its rugged, yellow and black striped body with a red posterior horn, while the adult transitions into a creature with shades of grey, brown, and black veiled wings. Indigenous to tropical climates, this species primarily feeds on the leaves of Apocynaceae family plants during its larval stage, and as an adult, it exhibits a promiscuous pollen-transfer behavior, which contributes to plant biodiversity by pollinating a variety of tropical flora.
