Parhelophilus integer
In 3 days ~10%
Parhelophilus integer, the shiny bog fly, is a rare species of syrphid fly observed in the Eastern United States. Hoverflies can remain nearly motionless in flight. The adults are also known as flower flies, for they are commonly found on flowers from which they get both energy-giving nectar and protein-rich pollen. The larvae of this genus are the long tailed "rat-tailed" type. Wikipedia →

Rare
Under 5% of wildlife watchers report a Shiny Bog Fly sighting in Washington on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 1649th most-seen of the 1807 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 Shiny Bog Fly in Washington on a given day, so our monthly data shows no clear season.
Between 3 and 6 pm
Across all the parks we cover, that three-hour window holds the most Shiny Bog Fly sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.

Of the 3 cities where we can rate Shiny Bog Fly sightings, Washington ranks 3rd at under 5%, level with the leaders once rounded. The best odds are in Boston (United States, under 5%) and Toronto (Canada, under 5%).
GBIF citizen-science records
It is estimated from how often the Shiny Bog Fly is recorded against all the insects logged in Washington (6 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.
