Eutricopis nexilis, the white-spotted midget, is a moth of the family Noctuidae. The species was first described by Herbert Knowles Morrison in 1875. It is found in North America from Nova Scotia and New England west across southern Canada to southern Vancouver Island, north to Yukon and south in the mountains to California and Colorado.
The wingspan is 18–20 mm. Adults are on wing from May to July. The larvae feed on Antennaria species. Wikipedia →

Rare
Under 5% of wildlife watchers report a White-Spotted Midget sighting in Yosemite National Park on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 192nd most-seen of the 227 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
In that month about 10% of wildlife watchers report a White-Spotted Midget in Yosemite National Park on a given day, against under 5% in August to June, the lowest months. That is one of Yosemite National Park's driest months, with about 25 mm of rain against 220 mm in January.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most White-Spotted Midget sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 2
Of the 2 parks where we can rate White-Spotted Midget sightings, Yosemite National Park ranks 2nd at under 5%. The best odds are in Rocky Mountain National Park (United States, about 10%).
GBIF citizen-science records
It is estimated from how often the White-Spotted Midget is recorded against all the insects logged in Yosemite National Park (6 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.
