Heliconius erato
In 3 days ~30% in a week ~50%
Heliconius erato, or the red postman, is one of about 40 neotropical species of butterfly belonging to the genus Heliconius. It is also commonly known as the small postman, the red passion flower butterfly, or the crimson-patched longwing. It was described by Carl Linnaeus in his 1758 10th edition of Systema Naturae.
H. erato exhibits Müllerian mimicry with other Heliconius butterflies such as Heliconius melpomene in order to warn common predators against attacking, which contributes to its surprising longevity. It also has a unique mating ritual involving the transfer of anti-aphrodisiacs from males to females. Its host plants are various passion flower (Passiflora) vine species.
Recent field work has confirmed the relative abundance of this butterfly. H. erato is a neotropical species, found from southern Texas to northern Argentina and Paraguay, and resides on the edges of tropical rainforests. It is philopatric, having a particularly restricted home range. In areas of dense population in Trinidad, some home ranges are only separated by 30 yards, but H. erato rarely travels to neighboring home ranges.

With luck
About 10% of wildlife watchers report a Red Postman sighting in Maceió on a given day, based on 14 verified sightings from GBIF citizen-science data. It is the 19th most-seen of the 67 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
January, June, September and November
In those months about 20% of wildlife watchers report a Red Postman in Maceió on a given day, against under 5% in February–April, October and December, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Red Postman sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
14th of 22
Of the 22 cities where we can rate Red Postman sightings, Maceió ranks 14th at about 10%. The best odds are in Porto Alegre (Brazil, about 30%), Valencia (Venezuela, about 20%) and João Pessoa (Brazil, about 20%).
Same family: Nymphalidae
The closest relatives of the Red Postman that you can see in Maceió (family Nymphalidae, Brush-footed Butterflies) are White Peacock (about 30%), Mexican Fritillary (about 20%) and Red Cracker (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Red Postman is recorded against all the insects logged in Maceió (14 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.
