Papilio troilus, the spicebush swallowtail or green-clouded butterfly, is a common black swallowtail butterfly found in North America. It has two subspecies, Papilio troilus troilus and Papilio troilus ilioneus, the latter found mainly in the Florida peninsula. The spicebush swallowtail derives its name from its most common host plant, the spicebush, members of the genus Lindera.
The family to which spicebush swallowtails belong, Papilionidae, or swallowtails, include the largest butterflies in the world. The swallowtails are unique in that even while feeding, they continue to flutter their wings. Unlike other swallowtail butterflies, spicebushes fly low to the ground instead of at great heights.
The spicebush swallowtail is found only in the eastern US and southern Ontario, but occasionally strays as far as the American plains states, Cuba, Manitoba and Colorado. While still larvae, spicebush swallowtails remain on the leaf of the plant on which they were laid. As adults, the butterflies do not limit their flight geographically and instead are motivated mostly by availability of water and nectar and mates within the species' range.

Possible
About 20% of wildlife watchers report a Spicebush Swallowtail sighting in Orlando on a given day, based on 180 verified sightings from GBIF citizen-science data. It is the 6th most-seen of the 294 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
August and September
In those months about 30% of wildlife watchers report a Spicebush Swallowtail in Orlando on a given day, against under 5% in November, the lowest month. Those are among Orlando's wettest months, with about 180 mm of rain a month against 50 mm in November.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Spicebush Swallowtail sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 11 cities where we can rate Spicebush Swallowtail sightings, Orlando has the highest daily chance: about 20%. Next come Houston (United States, about 10%) and Washington (United States, about 10%).
Same genus: Papilio
The closest relatives of the Spicebush Swallowtail that you can see in Orlando (genus Papilio, Common Swallowtails) are Eastern Tiger Swallowtail (about 10%), Eastern Giant Swallowtail (about 10%) and Black Swallowtail (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Spicebush Swallowtail is recorded against all the insects logged in Orlando (180 verified sightings), 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.
