Battus ingenuus, the Dyar's swallowtail or confused swallowtail, is a species of butterfly in the family Papilionidae. Battus ingenuus has a wingspan of about 82–95 millimetres (3.2–3.7 in). The uppersides of the wings are basically black with greenish reflections and pale green patches on the hindwings, while the undersides are mainly brownish, with red and white spots on the edges of the hindwings. The body is blackish, with yellow spots on the sides of the thorax and the abdomen and a few white spots on the underside of the abdomen. Males have a pale yellowish-greenish upper abdomen.
Battus ingenuus is present from southeastern Mexico to eastern Venezuela (Belize, Colombia, Costa Rica, Ecuador, El Salvador, Honduras, Nicaragua, Panama, Peru and Trinidad). Battus ingenuus can be found from low elevations up to moderate elevations in the Andes, at about 900 metres (3,000 ft) above sea level. In monsoonal areas of Costa Rica, the habitat is known as tropical deciduous forest, where most of the trees lose their leaves at the end of the dry season.
The larvae feed on Aristolochia constricta. As the caterpillars feed... Wikipedia →

Rare
Under 5% of wildlife watchers report a Dyar's Swallowtail sighting in Arenal Volcano National Park on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 256th most-seen of the 302 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.
April, June–July and December
In those months about 10% of wildlife watchers report a Dyar's Swallowtail in Arenal Volcano National Park on a given day, against under 5% in January–March, May and August–November, the lowest months.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Dyar's 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.
6th of 6
Of the 6 parks where we can rate Dyar's Swallowtail sightings, Arenal Volcano National Park ranks 6th at under 5%. The best odds are in Bastimentos Island National Marine Park (Panama, about 20%), Santa Rosa National Park (Costa Rica, about 10%) and Braulio Carrillo National Park (Costa Rica, about 10%).
GBIF citizen-science records
It is estimated from how often the Dyar's Swallowtail is recorded against all the insects logged in Arenal Volcano National Park (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.
