In 3 days ~10%
Drosophila busckii is a species of fruit fly that is native to North America, though it now also occurs in Asia, Europe, Oceania and South America. It can be identified by the presence of dark stripes on the thorax (including a trident shape on the mesonotum) and the wings being transparent with no markings. Mostly it is associated with rotten potatoes. In the laboratory they are normally reared on Wheeler-Clayton food. Wikipedia →

Rare
Under 5% of wildlife watchers report a Drosophila busckii sighting in Washington on a given day, based on 10 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 Drosophila busckii in Washington on a given day, so our monthly data shows no clear season.
Yes
Of the 3 cities where we can rate Drosophila busckii sightings, Washington has the highest daily chance: under 5%. Next come San Francisco (United States, under 5%) and Los Angeles (United States, under 5%).
GBIF citizen-science records
It is estimated from how often the Drosophila busckii is recorded against all the insects logged in Washington (10 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.
