Parides montezuma, the Montezuma's cattleheart, is a butterfly in the family Papilionidae. It is native to the Americas. The upperside of the wings is black, without a band and with one row of red crescents along the hindwing margin. The underside of the wings is almost the same as the upperside. A full description is provided by Rothschild, W. and Jordan, K. (1906)
P. montezuma is found in dry forests from Mexico to Costa Rica, occurring from sea level to 700 m (2,300 ft). It is rare in Costa Rica, being more common northward. It is not threatened. Aristolochia acanthophylla Aristolochia foetida – Jalisco Dutchman's pipe

With luck
About 10% of wildlife watchers report a Montezuma's Cattleheart sighting in Guadalajara on a given day, based on 56 verified sightings from GBIF citizen-science data. It is the 35th most-seen of the 229 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 50%, if each day is a fresh chance.
August and September
In those months about 20% of wildlife watchers report a Montezuma's Cattleheart in Guadalajara on a given day, against under 5% in November to May, the lowest months. Those are among Guadalajara's wettest months, with about 160 mm of rain a month against almost none in April.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Montezuma's Cattleheart sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Guadalajara, in our data
Guadalajara is the only city on Wallace's Line with enough records to rate Montezuma's Cattleheart sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Montezuma's Cattleheart is recorded against all the insects logged in Guadalajara (56 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.
