Pandorus Sphinx Moth Overview
Identification
The Pandorus Sphinx moth, scientifically known as Eumorpha pandorus, is a fascinating species belonging to the Sphingidae family. It is native to North America and can be found in various regions across the continent. They are characterized by their vibrant colors and unique patterns, making them easily distinguishable from other moths.
Their appearances vary, with some individuals exhibiting:
- Mossy green tinge, sometimes appearing pink or white

- Wingspans of up to 4.5 inches for females, slightly smaller for males
The forewings of the Pandorus Sphinx moth display interesting patterns that aid in identification. These patterns include:
- Dark brown or gray forewings, variably suffused with light gray
- Jagged subterminal lines emphasized by pale scales in the terminal area of the forewing
Pandorus Sphinx moths are just one of the many remarkable species within the sphinx moths group. While other sphinx moths share some of the Pandorus Sphinx’s characteristics, a quick comparison highlights differences:
Moth Species | Color | Forewing Features |
---|---|---|
Pandorus Sphinx | Pink, green, or white | Mossy green or pink, with jagged subterminal lines |
Hog Sphinx | Gray or brown | Lack subterminal lines, distinct banding |
In summary, the Pandorus Sphinx moth is a captivating and easily recognizable moth species native to North America, identifiable by its unique colors, patterns, and wing features.
Life Cycle and Development
Eggs and Larvae
The life of a Pandorus Sphinx moth begins as an egg. These eggs are laid by the female moth on the leaves of host plants, primarily grapevines and Virginia creepers. Once the eggs hatch, the larvae, or caterpillars, emerge and start feeding on the leaves. The caterpillars are green and have a long, curved horn (also known as a caudal horn or tail) at the end of their abdomen. During this stage, the caterpillars go through several instars, or developmental stages, shedding their skin as they grow. In each instar, the color of the caterpillar may vary, and some may have yellow stripes along their bodies.
Pandorus Sphinx caterpillar features:
- Green color
- Long, curved horn/tail on the abdomen
- Can have yellow stripes
Pupa and Adult
After reaching maturity, the caterpillar forms a pupa, usually in the soil beneath the host plant. It remains in the pupal stage for about 2 to 3 weeks. From the pupa, an adult Pandorus Sphinx moth emerges. These moths are in the family Sphingidae and have a long, slender abdomen and a wingspan that ranges from 3 to 4 inches. The adults are strong fliers with elongated forewings, often featuring shades of brown, green, or pink. These moths are most active at dusk, hovering around flowers to feed on nectar through their long proboscis.
Pandorus Sphinx moth characteristics:
- Family Sphingidae (Lepidoptera order, Insecta class)
- Long, slender abdomen
- 3 to 4-inch wingspan
- Elongated forewings
- Active at dusk
Comparison of Pandorus Sphinx moth life stages:
Stage | Features |
---|---|
Eggs | Laid on host plant leaves; hatch into caterpillars |
Caterpillars | Green with long, curved horn/tail; feed on leaves; go through several instars |
Pupa | Formed in soil; lasts 2 to 3 weeks |
Adult Moth | Long, slender abdomen and elongated forewings; 3 to 4-inch wingspan; active at dusk |
It’s important to note that Pandorus Sphinx moths are not considered poisonous and their caterpillars pose no threat to humans. They mainly feed on foliage and occasionally on fruits, making them minor pests in some areas.
Habitat and Distribution
The Pandorus Sphinx Moth (Family Sphingidae) is a large, striking moth with a notable distribution across North America. It can be found in habitats ranging from southern Texas to Wisconsin, Nova Scotia, and southern Ontario1. Typical habitats for this moth include woodlands, open or wooded areas near rivers, and suburban gardens2.
Adult Pandorus Sphinx Moths are active from early spring to mid-summer, with wingspans reaching up to 4 ½ inches1. They have a mossy green tinge and sport brown, intricate patterns on their wings1. The moths have long proboscises and are known to fly from flower to flower, feeding on nectar3.
Species characteristics:
- Potentially large wingspan: up to 4 ½ inches
- Colors: mossy green and brown
- Distribution: North America
- Habitat: woodlands, riverbanks, suburban gardens
The larvae of the Pandorus Sphinx Moth feed on Virginia creeper and wild grapes4. These moths are not considered poisonous or harmful to humans, so no need to worry if you encounter one.
Interaction with Humans and Environment
Gardens and Vineyards
The Pandorus Sphinx Moth, known for its camouflage, feeds on a variety of plant species in gardens and vineyards, such as Vitis spp., Parthenocissus quinquefolia, and Ampelopsis spp. Their larval stage is known to feed on foliage of these plants, including grapevines (Vitis spp.) and Virginia Creeper (Parthenocissus quinquefolia).
While some damage to plant leaves might occur, it is typically not severe enough to significantly impact the health of the plants.
Attraction to Lights
Pandorus Sphinx Moths are attracted to lights at night. They are often found near residential areas, drawn to porch lights and streetlights.
Conservation Status
The Pandorus Sphinx Moth is a common species with a wide distribution, ranging from Nova Scotia to South Florida and South Texas. There is no known threat to their population, and no conservation concerns at this time.
Key Features:
- Green to brown caterpillars
- Camouflage with foliage
- Attraction to light

Thank you WTB and Phil for helping me identify my moth visitor to the patio the other night. It is always exciting to see something new in the yard. It must be the season for moths as a hummingbird moth “bumped” into me this afternoon!
Love the website…and thank you again.

Thanks for helping me identify the caterpillar I found this morning. It looks exactly like the pinkish/orange one on your site. It has the single eyespot on one end and about 6 eyespots on each side. It seemed to be digging in the dirt, I assumed it was about to pupate. Pandorus Sphinx.
