hawkmoths

Hawkmoths, or hawk moths, belong to the family Sphingidae within the order Lepidoptera. They are known for their rapid, powerful flight and streamlined bodies. Many species can hover like hummingbirds while feeding on nectar with a long, coiled proboscis. The wings are typically narrow and pointed, and the hindwings may be brightly marked or hidden under the forewings. Adults occur worldwide, with greatest diversity in the tropics.

Lifecycle: Hawkmoths undergo complete metamorphosis. Eggs are laid on host plants; larvae (caterpillars) are usually large and have a horn at the rear, earning some species the common name “hornworms.” Caterpillars often display striking color patterns. Pupation occurs in leaf litter or soil, after which the adult emerges.

Ecology: Hawkmoths are important nocturnal pollinators in many ecosystems. Some species have coevolved with long-tongued flowers. Classic example is Darwin’s hawk-moth Xanthopan morganii praedicta, associated with the Madagascar orchid Angraecum sesquipedale. Some species migrate long distances. Notable hawkmoths include Acherontia atropos (death’s-head hawkmoth), which has a skull-like pattern on the thorax and may raid beehives; the elephant hawk-moth Deilephila elpenor; and the hummingbird hawk-moth Macroglossum stellatarum, which can hover and feed during the day.

Human interactions: Some larvae, such as the tobacco hornworm Manduca sexta, are agricultural pests and widely used in research. Adults are of interest to lepidopterists and ecologists for their sensory abilities and pollination roles. The family Sphingidae comprises more than 1,000 described species across many genera.
