About the White-Lined Sphinx

Hyles lineata, also known as the white-lined sphinx moth, is a moth of the family Sphingidae. They are sometimes known as a "hummingbird moth" because of their bird-like size (2–3 inch wingspan) and flight patterns. As caterpillars, they have a wide range of color phenotypes but show consistent adult coloration. With a wide geographic range throughout Central and North America, H. lineata is known to feed on many different host plants as caterpillars and pollinate a variety of flowers as adults.

Larvae are powerful eaters and are known to form massive groupings capable of damaging crops and gardens. As adults, they use both visual and olfactory perception to locate plants from which they collect nectar. Hyles lineata is one of the most abundant hawk moths in North America and has a very wide geographic range. This range extends from Central America to southern Canada through Mexico and most of the United States. Some regions of South Asia like Sindh, Pakistan are reported to have habitats for these moths. They can also be found occasionally in the West Indies. Rarely, specimens have also been reported in Eurasia and Africa.

In those months about 10% of wildlife watchers report a White-Lined Sphinx in Yellowstone National Park on a given day, against under 5% in October to April, the lowest months.

What time of day is best to see a White-Lined Sphinx?

Across all the parks we cover, that three-hour window holds the most White-Lined Sphinx sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.

Where does the White-Lined Sphinx sighting chance come from?

GBIF citizen-science records

It is estimated from how often the White-Lined Sphinx is recorded against all the insects logged in Yellowstone National Park (21 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
