Celithemis fasciata
In 3 days ~10% in a week ~20%
Celithemis fasciata, commonly known as the banded pennant, is a species of dragonfly in the skimmer family. It is native to the United States, where it is found in the south-central, southeastern, and eastern regions. The extensive, sharply defined black markings on its wings are distinctive, but the pattern varies considerably; individuals from the northern part of its range tend to have less wing coloration. It is about 33 mm (1.3 in) long.
It lives around ponds, lakes, and ditches. Wikipedia →

Rare
Under 5% of wildlife watchers report a Banded Pennant sighting in Boston on a given day, based on 23 verified sightings from GBIF citizen-science data. It is the 480th most-seen of the 1200 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.
July and August
In those months about 10% of wildlife watchers report a Banded Pennant in Boston on a given day, against under 5% in September to June, the lowest months.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Banded Pennant sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 3 cities where we can rate Banded Pennant sightings, Boston has the highest daily chance: under 5%. Next come Washington (United States, under 5%) and Austin (United States, under 5%).
GBIF citizen-science records
It is estimated from how often the Banded Pennant is recorded against all the insects logged in Boston (23 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.
