Metalectra discalis, the common fungus moth, is a moth of the family Erebidae. The species was first described by Augustus Radcliffe Grote in 1876. It is found in North America from Wisconsin to Quebec and Maine, south to Florida, west to Texas and Missouri, north to Ontario.
The wingspan is 20–29 mm. Adults are on wing from May to September in the south and from June to August in the north. There are probably two or more generations per year. Larvae have been recorded on bracket fungi and probably feed on other persistent fungi as well. Wikipedia →

Rare
Under 5% of wildlife watchers report a Common Fungus Moth sighting in Boston on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 888th 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 Common Fungus Moth in Boston on a given day, so our monthly data shows no clear season.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Common Fungus Moth sightings with a recorded time, and nearly all of them come between 6 pm and 6 am: it is mostly seen at night.
Among the best
Of the 5 cities where we can rate Common Fungus Moth sightings, Boston ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Baltimore (United States, under 5%).
Same family: Erebidae
The closest relatives of the Common Fungus Moth 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 Common Fungus Moth is recorded against all the insects logged in Boston (7 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.
