Halictus ligatus is a species of sweat bee from the family Halictidae, among the species that mine or burrow into the ground to create their nests. H. ligatus, like Lasioglossum zephyrus, is a primitively eusocial bee species, in which aggression is one of the most influential behaviors for establishing hierarchy within the colony, and H. ligatus exhibits both reproductive division of labor and overlapping generations.
Halictus ligatus was originally described by Thomas Say in 1837. The genus name Halictus refers to a group of sweat bees of the family Halictidae and order Hymenoptera known for their eusocial behavior and underground nesting. Within Halictidae, the subfamily Halictinae is unique for the substantial diversity in social behavior exhibited among species or within species, such as in H. rubicundus. For instance, species of this subfamily may exhibit either solitary nesting, communal nesting, cleptoparasitism, social parasitism, or primitive eusociality similar to H. ligatus.
The appearance of H. ligatus individuals closely resembles other members of the genus Halictus. These individuals are easily differentiated... Wikipedia →

With luck
About 10% of wildlife watchers report a Ligated Furrow Bee sighting in Denver on a given day, based on 150 verified sightings from GBIF citizen-science data. It is the 43rd most-seen of the 461 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.
July and August
In those months about 20% of wildlife watchers report a Ligated Furrow Bee in Denver on a given day, against under 5% in November to April, the lowest months. Those are among Denver's wettest months, with about 55 mm of rain a month against 15 mm in January.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Ligated Furrow 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.
6th of 28
Of the 28 cities where we can rate Ligated Furrow Bee sightings, Denver ranks 6th at about 10%. The best odds are in Valencia (Venezuela, about 20%), Boston (United States, about 20%) and Minneapolis [Saint Paul] (United States, about 20%).
GBIF citizen-science records
It is estimated from how often the Ligated Furrow Bee is recorded against all the insects logged in Denver (150 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.
