Sphinx Moths (Hawk Moths) Missouri Department of Conservation

August 27,2024

Sphinx moths are usually large and heavy bodied, with a long, pointed abdomen. They often hover near flowers, feeding on nectar via a very long proboscis (mouth tube or “tongue”). The forewings are generally long and pointed, although some species have angled or irregular margins. The antennae tend to get gradually wider, then narrow again toward the tip, and the comblike extensions (pectinations) of the antennae are usually short. Most sphinx moths are nocturnal, but some are most active at dawn and dusk, or during the day. The day-active species often mimic bees or hummingbirds. Sphinx moth caterpillars are often called hornworms, because they usually have a stiff, pointy horn on the rear end. They often rest with the thorax raised into the air and the head tilted downward, which reminded people of the posture of sphinx statues from ancient Egypt and elsewhere.
