Rare
Under 5% of wildlife watchers report a Harlequin Darner sighting in Boston on a given day, based on 20 verified sightings from GBIF citizen-science data. It is the 493rd 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.
May and June
In those months about 10% of wildlife watchers report a Harlequin Darner in Boston on a given day, against under 5% in July to April, the lowest months.
Only Boston, in our data
Boston is the only city on Wallace's Line with enough records to rate Harlequin Darner sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Harlequin Darner is recorded against all the insects logged in Boston (20 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.
