Battus lycidas is a species of butterfly in the family Papilionidae native to the Neotropical realm. It is commonly known as Cramer's swallowtail, the Lycidas swallowtail, and the yellow-trailed swallowtail. The wingspan of Battus lycidas can reach 10–11 millimetres (0.39–0.43 in). Wings are basically black, with yellow markings and a greenish structure-colour. The hind wings are tailless. This species shows a sexual dimorphism, as in males hind wings have anal androconial creamy yellow patches and the abdomen is yellow cream, while in the females hind wings have faint pale yellow spots forming a discontinuous strip in the middle area. Little is known about this species, but it is not considered threatened. Adults fly in May and June visiting flowers of Warscewiczia coccinea (Rubiaceae) and blooms of Vochysia guatemalensis (Vochysiaceae). The larvae of Battus lycidas feed on Aristolochia huberiana. and on Aristolochia constricta.
This species can be found from Mexico to northern Bolivia and southern Pará, Brazil. It is rare in Costa Rica. These butterflies prefer the canopy, the margins of streams and clearings, at an elevation of... Wikipedia →

Rare
Under 5% of wildlife watchers report a Cramer's Swallowtail sighting in Parque Natural Metropolitano on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 100th most-seen of the 114 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.
January and May–June
In those months about 10% of wildlife watchers report a Cramer's Swallowtail in Parque Natural Metropolitano on a given day, against under 5% in February–April and July–December, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Cramer's Swallowtail sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Only Parque Natural Metropolitano, in our data
Parque Natural Metropolitano is the only park on Wallace's Line with enough records to rate Cramer's Swallowtail sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Cramer's Swallowtail is recorded against all the insects logged in Parque Natural Metropolitano (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.
