![]() That pollen can then be spread to flowers farther than 18 miles away as the moth travels along its feeding route.Īt the Smithsonian’s National Museum of Natural History, there are over 25,000 specimens of hawk moths which are closely related to butterflies. When a hawk moth drinks from a flower, its proboscis picks up pollen. Hawk moths are known for their ability to travel incredible distances and for their extremely long proboscises - straw-like tongues from which they guzzle nectar. (Smithsonian)īees and butterflies are famous pollinators, but there’s another insect who deserves its share of the spotlight this Pollinator Week. There are over 1450 species of hawk moths in total on Earth. If you live outside of Iowa please do not submit a sample without contacting the Plant & Insect Diagnostic Clinic.The National Museum of Natural History’s Lepidoptera collection holds up to half of the world's species of hawk moths, important pollinators for many wild ecosystems. Please see our website for current forms, fees, and instructions on preserving and mailing insects.Ĭontact information for each states diagnostic laboratory for U.S. The Iowa State University Plant & Insect Diagnostic Clinic will identify your insect, provide information on what it eats, life cycle, and if it is a pest the best ways to manage them. Just enjoy the show! Do you live in Iowa and have an insect you would like identified? Even the hornworm caterpillar stage of most hummingbird moths is of relatively minor importance. Their nectar-sipping activity causes no harm to the flowers. Hummingbird moths are completely harmless. Whitelined sphinx moths are as likely to fly during the day as they are at twilight. The delicate pink coloration of the hind wings is visible when the moths are hovering at flowers. This is a stout-bodied, brown moth with a wingspan of 2.5 to 3.5 inches. The most commonly observed hummingbird-like moth is the whitelined sphinx, Hyles lineata, so named for the broad white stripe running diagonally to the outer tip of each front wing. The rolling and unrolling action of the proboscis can be compared to the movements of a party noisemaker. When the moth is done feeding, muscles coil the proboscis back into resting position. The tightly spiraled proboscis is extended and held stiff by internal fluid pressure as the moth reaches for the nectar supply at the base of flowers. ![]() When not in use the proboscis is coiled against the underside of the head. The well-developed proboscis of hummingbird moths is an extendable, beaklike hollow tube or tongue that may be several inches in length and often as long as or longer than the moth’s body. A tiny amount of nectar is withdrawn during a brief visit to each flower. They are capable of hovering in mid air for extended periods and flying just in front of flowers as they sip nectar through their extended proboscis. Sphinx moths are strong fliers with a very rapid wingbeat. There are approximately 125 different species of sphinx moths in the U.S. Sphinx moths may have a wingspread of up to 6 inches though a more common size in Iowa is a 2 to 4.5 inch wingspan. The wings have the shape of a wide, flat triangle ending in an acute angle at the farthest point. These are medium to large-sized moths with a robust body and narrow, elongate front wings. Sphinx moths, also known as hawk moths, are from the family Sphingidae. ![]() The name hummingbird moth is a nickname used for several different species of sphinx moths. If you don’t look closely at the dark color and the antennae at the front of the head, you can be easily fooled into believing these really are hummingbirds! They hover in mid-air and flit from one flower to the next. However, it is remarkable how much the moths behave like hummingbirds. The moths in question are large and about the size of a hummingbird. ![]() Favorite flowers include deep-throated blossoms such as petunias and hosta blooms. One of my favorites is the large dark moths that look and act like hummingbirds, feeding on nectar from flowers around dusk. There is so much to enjoy in late summer. ![]()
