Sphecodina abbottii, or Abbott's sphinx, is a moth of the family Sphingidae. The species was first described by William Swainson in 1821. It lives in central and eastern North America, but is not known to be present in most of Florida.

The underwings have a strong yellow band and in flight, the moth buzzes, appearing like a bee. The forewings are violet grey when fresh and have a "barklike pattern of swirling black lines" according to David Beadle and Seabrooke Leckie.

Early instars are a pale greenish white, with at first a horn, but later a brown knob near the hind end. Final instars (75 mm in length) come in two patterns: one has brown bands such that there are ten large pale green spots on the back and an eyespot on the rear. This form may mimic grapes. Others are completely brown, with a wood-grain patterning, and with the rear eyespot. In the final instar the knob looks... Wikipedia →

Rare
Under 5% of wildlife watchers report an Abbott's Sphinx sighting in Shenandoah National Park on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 630th most-seen of the 723 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
June and July
In those months about 10% of wildlife watchers report an Abbott's Sphinx in Shenandoah National Park on a given day, against under 5% in August to May, the lowest months.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Abbott's 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.
2nd of 2
Of the 2 parks where we can rate Abbott's Sphinx sightings, Shenandoah National Park ranks 2nd at under 5%. The best odds are in Great Smoky Mountains National Park (United States, about 10%).
Same family: Sphingidae
The closest relatives of the Abbott's Sphinx that you can see in Shenandoah National Park (family Sphingidae, Sphinx Moths) are Snowberry Clearwing (about 20%), Hummingbird Clearwing (about 10%) and Virginia Creeper Sphinx (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Abbott's Sphinx is recorded against all the insects logged in Shenandoah National Park (5 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.
