Bombus ephippiatus
In 3 days ~80% in a week >90%
Bombus ephippiatus is a species of bumblebee native to Mexico and Central America. This is a variable species. There are a number of color polymorphisms, with body hairs in shades of white, yellow, orange, red, brown, and black. Its species boundaries are not entirely clear. Some forms are similar to Bombus wilmattae, which may actually be the same species. There may also be some similar specimens in the area that are an as yet undescribed species.
This bee feeds on many kinds of flowers. It is active year-round in some areas. It generally occupies pine-oak forest and other kinds of mountain forest habitat. Its restriction to high-elevation regions may have produced physical isolation that led to its many color polymorphisms.
It is an efficient pollinator of tomato plants. The overcollection of queens from the wild for use in agricultural operations is a potential threat to the species. Wikipedia →

Likely
About 40% of wildlife watchers report a Mesoamerican Bumble Bee sighting in Los Quetzales National Park on a given day, based on 142 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the most-seen of the 56 insects we can rate there. Over three days the chance rises to about 80%, and over a week to over 90%, if each day is a fresh chance.
March
In that month about 60% of wildlife watchers report a Mesoamerican Bumble Bee in Los Quetzales National Park on a given day, against about 30% in January, June, August and October, the lowest months. That is one of Los Quetzales National Park's driest months, with about 120 mm of rain against 730 mm in October.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Mesoamerican Bumble Bee sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 9
Of the 9 parks where we can rate Mesoamerican Bumble Bee sightings, Los Quetzales National Park ranks 3rd at about 40%. The best odds are in Irazú Volcano National Park (Costa Rica, about 70%) and Reserva de la Biosfera Mariposa Monarca (Mexico, about 50%). All parks ranked.
GBIF citizen-science records
It is estimated from how often the Mesoamerican Bumble Bee is recorded against all the insects logged in Los Quetzales National Park (142 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.
