Schinia florida
In 3 days ~10% in a week ~20%
Schinia florida, the primrose moth, is a moth of the family Noctuidae described by Achille Guenée in 1852. Its range includes most of temperate North America aside from the west coast. Adults have a pink head and pale yellow to creamy white thorax and abdomen. The forewings are pink with pale yellow markings. The hindwings are creamy white. The wingspan is about 30 mm.
Eggs are laid on the flower buds of evening-primroses (Oenothera spp.), which are the larval host plants. Eggs hatch 4–5 days after being laid. Larvae go through five instars before burrowing into the ground to pupate and overwinter.
There is one generation per year, with the adult flight period timed to coincide with the bud development of its larval host plants. Adults are nocturnal, and often rest in the flowers of evening-primroses during the day. Wikipedia →

Rare
Under 5% of wildlife watchers report a Primrose Moth sighting in Salt Lake City on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 213th most-seen of the 242 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.
August
In that month about 10% of wildlife watchers report a Primrose Moth in Salt Lake City on a given day, against under 5% in September to July, the lowest months. That is one of Salt Lake City's driest months, with about 25 mm of rain against 70 mm in December.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Primrose Moth sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 6 cities where we can rate Primrose Moth sightings, Salt Lake City ranks 3rd at under 5%, level with the leaders once rounded. The best odds are in Montreal (Canada, under 5%) and Edmonton (Canada, under 5%).
GBIF citizen-science records
It is estimated from how often the Primrose Moth is recorded against all the insects logged in Salt Lake City (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.
