Rare
Under 5% of wildlife watchers report a Gray Half-Spot sighting in Boston on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 1063rd 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 Gray Half-Spot in Boston on a given day, so our monthly data shows no clear season.
Between 6 and 9 am
Across all the parks we cover, that three-hour window holds the most Gray Half-Spot sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 3 cities where we can rate Gray Half-Spot sightings, Boston ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Toronto (Canada, under 5%).
Same family: Noctuidae
The closest relatives of the Gray Half-Spot 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 Gray Half-Spot is recorded against all the insects logged in Boston (5 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.
