Tetrio sphinx

Tetrio sphinx

Pseudosphinx tetrio

A species of Pseudosphinx, Also known as Giant gray sphinx, Frangipani hornworm

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.

Life Cycle of Tetrio sphinx
Egg The eggs of tetrio sphinx are small, usually laid in clusters. They possess a protective outer layer and are the beginning of the life cycle. Color and shape vary but generally blend with the environment for protection.
Larva Upon hatching, the larva of tetrio sphinx is a caterpillar, focused on eating and growing. It has a cylindrical body, vibrant coloration for warning or camouflage, and undergoes several molts before pupation.
Pupal The pupa of tetrio sphinx is a dormant stage, enveloped in a cocoon or chrysalis. The pupa undergoes significant internal transformation, reorganizing its body structure for the adult stage.
Adult Emerging from the pupa, the adult tetrio sphinx has developed wings and reproductive organs. The body is fully formed and hardened, enabling flight for feeding and mating purposes.

How Can You Attract Tetrio sphinx
Adult tetrio sphinx are typically attracted to nectar-rich flowers, so using scented baits or artificial nectar can serve as effective lures.
Rectangle
Habitat Preferences of Tetrio sphinx Through Different Life Stages
The eggs of tetrio sphinx are typically found on the undersides of host plant leaves. Caterpillars prefer to feed on leaves of the Frangipani plant and can be found clinging to the stems or leaves. Pupae often burrow into the ground to metamorphose in a subterranean chamber. Adults, being strong fliers, are widespread but frequently visit flowers in search of nectar during dusk or at night. Therefore, to find the different growth stages of tetrio sphinx, you would inspect Frangipani plants for eggs and caterpillars, gently probe into the soil at the base of these plants for pupae, and search around nectar-rich flowers after sunset for adults.

How and Where Can You Find Tetrio sphinx at Different Life Stages
Egg Eggs of tetrio sphinx are typically laid on the underside of host plant leaves. To find them, inspect these areas on known host plants for small, spherical objects.
Larva Tetrio sphinx larvae are large, vividly colored caterpillars that can be found on or near their host plants. Look for them by searching the stems and leaves of these plants.
Pupal Tetrio sphinx pupate in the soil or leaf litter. To find the pupae, carefully search through the top layer of soil or leaf litter near the host plants without disturbing too much of the environment.
Adult Adult tetrio sphinx are strong fliers and are attracted to bright, fragrant flowers. To observe them, visit gardens or fields with abundant flowers during evening hours.

Pollination Behavior Reason
Eat Pollen Or Nectar
Tetrio sphinx is an exceptional pollinator, often observed at flowers where it feeds on pollen. It is drawn to blooms by visual cues such as vivid colors and distinct shapes. While taking in the nutritious pollen, tetrio sphinx inadvertently transfers it, fertilizing numerous plants in the process.
