Rare
Under 5% of wildlife watchers report a Wavy-Lined Fan-Foot sighting in Boston on a given day, based on 10 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.
July
In that month about 10% of wildlife watchers report a Wavy-Lined Fan-Foot in Boston on a given day, against under 5% in August to June, the lowest months.
Between 9 pm and midnight
Across all the parks we cover, that three-hour window holds the most Wavy-Lined Fan-Foot sightings with a recorded time, and about 7 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Among the best
Of the 3 cities where we can rate Wavy-Lined Fan-Foot sightings, Boston ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Edmonton (Canada, under 5%).
Same family: Erebidae
The closest relatives of the Wavy-Lined Fan-Foot that you can see in Boston (family Erebidae, Underwing, Tiger, Tussock, and Allied Moths) are Isabella Tiger Moth (about 20%), Virginian Tiger Moth (about 10%) and Green Cloverworm Moth (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Wavy-Lined Fan-Foot is recorded against all the insects logged in Boston (10 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.
