Alucita montana
In 3 days ~10%
Alucita montana, the Montana six-plume moth, is a moth of the family Alucitidae. It was described by William Barnes and Arthur Ward Lindsey in 1921. It is found in North America from south-western Quebec and Vermont, west to British Columbia and south to Arizona, California and Texas.
The wingspan is 11–16 mm (0.43–0.63 in). The forewings are crossed by a wide median band, margined narrowly with white, which forks on the first two lobes. There is another band nearer the base on the first lobe which is not distinctly marked elsewhere, and an additional subterminal band which is narrower on the first two lobes. Between this and the median band there is a heavy costal spot which does not reach the inner margin of the first lobe. All of these marks are margined with white. The ground color is grayish tawny and the marks are very dark brown, as are the tips of the lobes. The hindwings are checkered with dark brown, tawny and white.
The larvae feed on Symphoricarpos species in the northern part of the range and Lonicera species in California. Wikipedia →

Rare
Under 5% of wildlife watchers report a Montana Six-Plume Moth sighting in San Francisco on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 679th most-seen of the 737 insects we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Montana Six-Plume Moth in San Francisco on a given day, so our monthly data shows no clear season.

GBIF citizen-science records
It is estimated from how often the Montana Six-Plume Moth is recorded against all the insects logged in San Francisco (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.
