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 Vancouver on a given day, based on 266 verified sightings from GBIF citizen-science data. It is the 27th most-seen of the 482 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.
June and July
In those months about 20% of wildlife watchers report an Orange-Legged Furrow Bee in Vancouver on a given day, against under 5% in September to February, the lowest months. Those are among Vancouver's driest months, with about 35 mm of rain a month against 210 mm in November.
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 21 cities where we can rate Orange-Legged Furrow Bee sightings, Vancouver ranks 5th at about 10%, level with the leaders once rounded. The best odds are in Minneapolis [Saint Paul] (United States, about 10%), Anchorage (United States, about 10%) and Salt Lake City (United States, about 10%).
Same order: Hymenoptera
The closest relatives of the Orange-Legged Furrow Bee that you can see in Vancouver (order Hymenoptera, Ants, Bees, Wasps, and Sawflies) are Common Eastern Bumble Bee (about 30%), Yellow-Faced Bumble Bee (about 30%) and Fuzzy-Horned Bumble Bee (about 20%), 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 Vancouver (266 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.
