In 3 days ~10% in a week ~30%
Raphia frater, the brother moth or simply the brother, is a moth of the family Noctuidae. It is found from Nova Scotia west, across the forested regions of Canada to British Columbia, south to Mississippi in the east. The southern limits in the west are uncertain due to confusion with several closely related species or forms.
The wingspan is 38–44 mm. Adults are on wing from April or May to August. There is one or two generations per year. The larvae mainly feed on aspen, but have also been recorded from alder, birch, cottonwood, and willow. Raphia frater frater (Prairie Provinces, in the east south of the Great Lakes region into Pennsylvania, Ohio and Indiana; In the West, it occurs south along mid-elevation mountain ranges of the Pacific Northwest into Washington, and southward along the Rocky Mountains. Specimens from high elevations in Colorado and New Mexico) Wikipedia →

Rare
Under 5% of wildlife watchers report a Brother Moth sighting in Austin on a given day, based on 69 verified sightings from GBIF citizen-science data. It is the 452nd most-seen of the 1624 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.
March–April and September
In those months about 10% of wildlife watchers report a Brother Moth in Austin on a given day, against under 5% in May–August and October–February, the lowest months.
Between 5 and 8 am
Across all the parks we cover, that three-hour window holds the most Brother Moth sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.

GBIF citizen-science records
It is estimated from how often the Brother Moth is recorded against all the insects logged in Austin (69 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.
