Rare
Under 5% of wildlife watchers report a Roland's Sallow sighting in Boston on a given day, based on 13 verified sightings from GBIF citizen-science data. It is the 668th 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.
March
In that month about 10% of wildlife watchers report a Roland's Sallow in Boston on a given day, against under 5% in April to February, the lowest months.
Among the best
Of the 4 cities where we can rate Roland's Sallow sightings, Boston ranks 3rd at under 5%, level with the leaders once rounded. The best odds are in Austin (United States, under 5%) and Dallas (United States, under 5%).
Same family: Noctuidae
The closest relatives of the Roland's Sallow that you can see in Boston (family Noctuidae, Cutworm Moths and Allies) are Large Yellow Underwing (about 10%), Armyworm Moth (about 10%) and American Copper Underwing (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Roland's Sallow is recorded against all the insects logged in Boston (13 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.
