They have also been reported as feeding on a member of the genus Piper.
A large species (12 to 14 cm (4.7 to 5.5 in) wingspan. The wings are narrow. The forewings are mostly brown. A yellow band runs from the tip, becoming narrower towards the back.

There is a row of yellow arcuate spots at the edge of the hind wings. A broad yellow band runs through the first half of the wing. Inside sits a black eyespot with blue-white dusting.

Possible
About 20% of wildlife watchers report a Thoas Swallowtail sighting in Maceió on a given day, based on 24 verified sightings from GBIF citizen-science data. It is the 5th most-seen of the 67 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.
May
In that month about 30% of wildlife watchers report a Thoas Swallowtail in Maceió on a given day, against under 5% in February–March and October, the lowest months. That is one of Maceió's wettest months, with about 180 mm of rain against 25 mm in November.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Thoas Swallowtail sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.

GBIF citizen-science records
It is estimated from how often the Thoas Swallowtail is recorded against all the insects logged in Maceió (24 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.
