Rare
Under 5% of wildlife watchers report a Dark Acrolophus sighting in Boston on a given day, based on 14 verified sightings from GBIF citizen-science data. It is the 612th 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.
September and October
In those months about 10% of wildlife watchers report a Dark Acrolophus in Boston on a given day, against under 5% in November to August, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Dark Acrolophus sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Boston, in our data
Boston is the only city on Wallace's Line with enough records to rate Dark Acrolophus sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Dark Acrolophus is recorded against all the insects logged in Boston (14 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.
