Rare
Under 5% of wildlife watchers report a Large Ectemnius sighting in Boston on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 888th 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Large Ectemnius in Boston on a given day, so our monthly data shows no clear season.
Among the best
Of the 4 cities where we can rate Large Ectemnius sightings, Boston ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Vancouver (Canada, under 5%).
GBIF citizen-science records
It is estimated from how often the Large Ectemnius is recorded against all the insects logged in Boston (7 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.
