Rare
Under 5% of wildlife watchers report an Epione Underwing sighting in Boston on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 783rd 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 an Epione Underwing in Boston on a given day, so our monthly data shows no clear season.
Between 10 pm and 1 am
Across all the parks we cover, that three-hour window holds the most Epione Underwing sightings with a recorded time, and about 9 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Only Boston, in our data
Boston is the only city on Wallace's Line with enough records to rate Epione Underwing sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Epione Underwing is recorded against all the insects logged in Boston (9 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.
