Battus polydamas, also known as the gold rim swallowtail, the Polydamas swallowtail or the tailless swallowtail, is a species of butterfly in the family Papilionidae. The species was first described by Carl Linnaeus in his 10th edition of Systema Naturae, published in 1758. Adults generally have black wings with yellow markings while the larval stage is mainly about consuming acids from toxic plants to make themselves unpalatable to predators. They are mainly found in the Neotropical region, and in many of the Caribbean islands.
The Polydamas swallowtail is widespread in the Neotropical realm throughout Mexico, Central and South America, the Caribbean, and in southern United States, including Texas and Florida. It also inhabits many Caribbean islands such as Jamaica, Cuba, Puerto Rico, Haiti and the Dominican Republic. Within this broad range, B. polydamas prefers habitats where they can access its larval host plants, particularly species in the genus Aristolochia. However, it is most often found in open woodlands, along the edges of forests, or abandoned fields, and occasionally in gardens with their preferable host plants.

GBIF citizen-science records
It is estimated from how often the Polydamas Swallowtail is recorded against all the insects logged in San José (54 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.
