With luck
About 10% of wildlife watchers report a Wavy-Lined Fan-Foot sighting in Acadia National Park on a given day, based on 8 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 270th most-seen of the 405 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
July and August
In those months about 10% of wildlife watchers report a Wavy-Lined Fan-Foot in Acadia National Park on a given day, against under 5% in September 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.
Only Acadia National Park, in our data
Acadia National Park is the only park on Wallace's Line with enough records to rate Wavy-Lined Fan-Foot sightings: about 10% of wildlife watchers there report one on a given day.
Same family: Erebidae
The closest relatives of the Wavy-Lined Fan-Foot that you can see in Acadia National Park (family Erebidae, Underwing, Tiger, Tussock, and Allied Moths) are Hickory Tussock Moth (about 30%), Brown-Tail Moth (about 20%) and Isabella Tiger Moth (about 20%), 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 Acadia National Park (8 verified sightings from 2019 to 2026), 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.
