Rare
Under 5% of wildlife watchers report a Thin-Lined Calligrapher sighting in Washington on a given day, based on 17 verified sightings from GBIF citizen-science data. It is the 878th most-seen of the 1807 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 Thin-Lined Calligrapher in Washington 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 Thin-Lined Calligrapher 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 4 cities where we can rate Thin-Lined Calligrapher sightings, Washington ranks 4th at under 5%, level with the leaders once rounded. The best odds are in Orlando (United States, under 5%), Houston (United States, under 5%) and Miami (United States, under 5%).
Same genus: Toxomerus
The closest relatives of the Thin-Lined Calligrapher that you can see in Washington (genus Toxomerus, Calligrapher Flies) are Eastern Calligrapher (about 10%), Margined Calligrapher (about 10%) and Maize Calligrapher (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Thin-Lined Calligrapher is recorded against all the insects logged in Washington (17 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.
