Halictus rubicundus, the orange-legged furrow bee, is a species of sweat bee found throughout the Northern Hemisphere. H. rubicundus entered North America from the Old World during one of two main invasions of Halictus subgenera. These invasions likely occurred via the Bering land bridge at times of low sea level during the Pleistocene epoch.
The species exhibits different social behaviors depending on climate: it is a solitary species in high elevations or latitudes where the season is short, but eusocial in other areas. Often, solitary and eusocial colonies appear simultaneously in the same population. These sweat bees are extensively studied for their variability in social behavior, which has become a model for social plasticity. This variability has contributed to an understanding of evolution of social behavior.
Halictus rubicundus is a species of Hymenoptera in the bee family Halictidae, more commonly known as sweat bees. This common name comes from their frequent attraction to perspiration. This species exhibits polymorphic social behavior that varies with environmental conditions, and other species of the family Halictidae are thought to have similar... Wikipedia →

With luck
About 10% of wildlife watchers report an Orange-Legged Furrow Bee sighting in Yellowstone National Park on a given day, based on 10 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 96th most-seen of the 160 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 and August–September
In those months about 10% of wildlife watchers report an Orange-Legged Furrow Bee in Yellowstone National Park on a given day, against under 5% in May, July and October–March, the lowest months.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Orange-Legged Furrow Bee sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 6 parks where we can rate Orange-Legged Furrow Bee sightings, Yellowstone National Park ranks 4th at about 10%, level with the leaders once rounded. The best odds are in Acadia National Park (United States, about 10%), Olympic National Park (United States, about 10%) and Glacier National Park (United States, about 10%).
Same order: Hymenoptera
The closest relatives of the Orange-Legged Furrow Bee that you can see in Yellowstone National Park (order Hymenoptera, Ants, Bees, Wasps, and Sawflies) are Vancouver Bumble Bee (about 10%), Red-Belted Bumble Bee (about 10%) and Nevada Bumble Bee (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Orange-Legged Furrow Bee is recorded against all the insects logged in Yellowstone National Park (10 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.
