Bombus ephippiatus
In 3 days ~20% in a week ~30%
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 →

With luck
About 10% of wildlife watchers report a Mesoamerican Bumble Bee sighting in Mexico City on a given day, based on 86 verified sightings from GBIF citizen-science data. It is the 106th most-seen of the 557 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.
April–May, July–August and December
In those months about 10% of wildlife watchers report a Mesoamerican Bumble Bee in Mexico City on a given day, against under 5% in January–March, June and September–November, the lowest months.
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.
2nd of 2
Of the 2 cities where we can rate Mesoamerican Bumble Bee sightings, Mexico City ranks 2nd at about 10%. The best odds are in Toluca (México, about 20%).
GBIF citizen-science records
It is estimated from how often the Mesoamerican Bumble Bee is recorded against all the insects logged in Mexico City (86 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.
