Plagioneurus univittatus
In 3 days ~10%
Plagioneurus is a genus of long-legged flies in the family Dolichopodidae. It contains only one species, Plagioneurus univittatus, and is the only member of the subfamily Plagioneurinae. The range of P. univittatus spans from the Eastern United States south to South America.
The genus name is derived from the Ancient Greek words πλάγιος (plágios, 'oblique') and νεῦρον (neûron, 'nerve'), referring to the unusual angle of the last part of the medial wing vein M, which converges with radial vein R4+5.
In the adults, the thorax is a metallic green, with a strong black stripe in the center, and the abdomen is black with white pruinose posterior bands. The wings are hyaline. Wikipedia →

Rare
Under 5% of wildlife watchers report a Plagioneurus univittatus sighting in Chicago on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 884th most-seen of the 978 insects we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Plagioneurus univittatus in Chicago on a given day, so our monthly data shows no clear season.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Plagioneurus univittatus sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.

Of the 3 cities where we can rate Plagioneurus univittatus sightings, Chicago ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Miami (United States, under 5%).
GBIF citizen-science records
It is estimated from how often the Plagioneurus univittatus is recorded against all the insects logged in Chicago (5 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.
