What Do Tersa Sphinx Caterpillars Eat?

Tersa sphinx moth caterpillars are voracious feeders that feed on various plants, including starclusters, buttonplants, firebush, Manettia, strongbark, and wild coffee. They are known to quickly consume plant leaves when they grow large. The Tersa Sphinx caterpillar, also known as hawk moths or hummingbird moths, has a diet mainly consisting of nectar from various flowers and consumes leaves of specific plants.

The Tersa Sphinx caterpillar larvae, growing to approximately 8cm, have varying colors and light or dark-colored eyespots on their abdomen. They are found in the United States, with one brood in the north from May-October and several broods in Florida and Louisiana from February-November. Their caterpillars feed on various plants, including smooth buttonplants, starclusters, Borreria, Catalpa, broadleaf buttonweed, candy corn vine, catalpa, firebush, and smooth buttonplant. They have also been reported from joe-pie weed.

Depending on the species, caterpillars can eat various vegetation, including tomatoes, which are the dreaded tomato hornworm. They can eat four-o’clock, apple, evening primrose, Fuchsia, Elm, Grape, Tomato, Purslane, and Clover leaves. Young caterpillars tend to feed toward the tops of the plants, with larger final instars found lower down and deeper into the plant. The Nessus sphinx moth hovers near flowers, collecting nectar during the day and at dusk. The caterpillars eat plants in the grape family, including Virginia.

How Does A Tersa Sphinx Moth Pupate?

At the conclusion of their larval stage, tersa sphinx moth caterpillars seek a suitable area to pupate, undergoing a metamorphosis to become pupae. This stage, which is crucial for their transformation into adult moths, sees the caterpillars not forming traditional cocoons but instead creating a protective pupal case. The pupation process lasts approximately two weeks, culminating in the emergence of adult moths.

This metamorphosis showcases fascinating behaviors, and videos and scientific articles delve into these transformations for educational insights. Xylophanes tersa, the species' scientific name, is part of the Sphingidae family and was first documented by Carl Linnaeus in 1771, primarily found from the United States to South America.

Tersa sphinx moths display a life cycle characterized by eggs typically laid singly on host plants, with larvae consuming leaves before burrowing into the soil or leaf litter to pupate. Interestingly, mature caterpillars may mimic snakes to deter predators.

The pupae, which can grow several inches long and have a distinct segmented body, usually stay beneath leaf litter during this phase. Depending on the environmental conditions, these moths can have multiple generations annually in regions like North Carolina. Ultimately, their unique method of pupation and metamorphosis contributes to the understanding of their life cycle and ecological significance.

How Do I Get Rid Of A Tersa Sphinx Caterpillar?

If you experience a large caterpillar infestation, consider using organic Thuricide, which specifically targets caterpillars. Many caterpillar species are attracted to particular host plants; for instance, Pentas serve as a host for the Tersa Sphinx. Pay attention to your Pentas next summer for any leaf damage and inspect closely for small caterpillars. Remove and destroy any found. Tersa Sphinx caterpillars can be challenging to manage due to their size, but using specialized insecticides or handpicking them off can be effective.

Spraying young caterpillars while they feed or treating foliage when larvae first appear is crucial. Specifically, "tomato" hornworms can be controlled using garden insecticides like carbaryl, permethrin, or spinosad. Alternatively, an inexpensive remedy for smaller caterpillars is a simple mixture of soap and water. Mix a small amount of organic liquid soap in warm water to create this solution. The Tersa Sphinx moth caterpillar transitions into a pupa, forming a protective casing in this stage.

Successful caterpillar control often requires a multifaceted approach; thus, we recommend multiple methods to address infestations. Maintaining a healthy garden through actions like pruning dead or diseased plants also aids in preventing infestations. Notably, despite their intimidating appearance, Tersa Sphinx caterpillars are harmless and can be easily removed from host plants. Regular monitoring for plant damage and droppings is essential to stay ahead of these pests.

Tersa Sphinx moths show adaptability, yet their uncommonness reinforces their status as special sightings within their geographical range.

What Is The Life Cycle Of A Tersa Sphinx Caterpillar?

The life cycle of the tersa sphinx moth (Xylophanes tersa) begins with the laying of eggs, typically on suitable host plants, occurring singly. Mature caterpillars, known for their size (4 to 5 inches) and vivid coloration, do not typically spin cocoons but instead burrow into soil or leaf litter to pupate. A few species may form a very thin cocoon on the ground surface. After a few weeks, they emerge as adults. The pupation process serves as a transitional stage from larva to adult, with the caterpillar forming a protective pupal case.

Tersa sphinx caterpillars are often startling to gardeners and can be found feeding on various vegetation, including tomatoes. Notably, the tomato hornworm is the larva of a sphinx moth. The term "sphinx" refers to their unique ability to retract their heads and thoracic segments into their abdomens, and they possess a distinctive black horn at their rear. Adults emerge from the pupal stage typically in spring, with pupation duration varying—around two weeks in summer, while those entering pupation in autumn will overwinter.

Throughout their development, these larvae are found from May to November, with adults primarily active at dusk to feed and lay eggs. Understanding the distinct characteristics and stages of their life cycle can aid in identifying both the caterpillars and pupae in gardens.
