Augochlorella aurata is a primitively eusocial species of sweat bee (bees attracted by the salt in human sweat) in the family Halictidae.

Like many members of Halictidae, the tip of the mandible of these bees is rounded and said to be shaped like a glove or mitten. This character distinguishes them from Augochlora pura that bears similar resemblance but have forked mandible tips. The propodeum is... Wikipedia →

Rare
Under 5% of wildlife watchers report a Golden Sweat Bee sighting in Boston on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 888th most-seen of the 1200 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Golden Sweat Bee in Boston on a given day, so our monthly data shows no clear season.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Golden Sweat 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 5 cities where we can rate Golden Sweat Bee sightings, Boston ranks 4th at under 5%, level with the leaders once rounded. The best odds are in Minneapolis [Saint Paul] (United States, under 5%), Denver (United States, under 5%) and Toronto (Canada, under 5%).
Same family: Halictidae

GBIF citizen-science records
It is estimated from how often the Golden Sweat Bee is recorded against all the insects logged in Boston (7 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.
