Battus philenor, the pipevine swallowtail or blue swallowtail, is a swallowtail butterfly found in North America and Central America. This butterfly is black with iridescent-blue hindwings. They are found in many different habitats, but are most commonly found in forests. Caterpillars are often black or red, and feed on compatible plants of the genus Aristolochia. They are known for sequestering acids from the plants they feed on in order to defend themselves from predators by being poisonous when consumed. The adults feed on the nectar of a variety of flowers. Some species of Aristolochia are toxic to the larvae, typically tropical varieties. While enthusiasts have led citizen efforts to conserve pipevine swallowtails in their neighborhoods on the West coast, the butterfly has not been the subject of a formal program in conservation or protected in legislation. The butterfly is however of "Special Concern" in Michigan, which is on the Northern limit of its range.
The pipevine swallowtail was first identified in 1771 by Linnaeus and originally was placed in the genus Papilo, as was typical for butterflies. In 1777, it was moved to the genus Battus by Scopoli. The... Wikipedia →

Rare
Under 5% of wildlife watchers report a Pipevine Swallowtail sighting in Orlando on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 191st most-seen of the 294 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
June and September
In those months about 10% of wildlife watchers report a Pipevine Swallowtail in Orlando on a given day, against under 5% in July–August and October–May, the lowest months. Those are among Orlando's wettest months, with about 190 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 Pipevine 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.
20th of 24
Of the 24 cities where we can rate Pipevine Swallowtail sightings, Orlando ranks 20th at under 5%. The best odds are in Sacramento (United States, about 30%), San Antonio (United States, about 30%) and Austin (United States, about 20%).
GBIF citizen-science records
It is estimated from how often the Pipevine Swallowtail is recorded against all the insects logged in Orlando (8 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.
