Macaria signaria, the dusky peacock, pale-marked angle or spruce-fir looper, is a moth of the family Geometridae. The species was first described by Jacob Hübner in 1809. Subspecies Semiothisa signaria signaria is found in Europe, Turkey, the Caucasus, Transcaucasia, the Ural, Siberia, Far East, Sakhalin, northern Iran and Japan. Subspecies Macaria signaria dispuncta is found in North America (from Yukon and Newfoundland to North Carolina, New Mexico, Arizona and California).
The wingspan is 20–28 mm. The moth flies from May to July depending on the location. The larvae feed on Picea abies and Larix sibirica. Wikipedia →

Rare
Under 5% of wildlife watchers report a Pale-Marked Angle sighting in Seattle on a given day, based on 10 verified sightings from GBIF citizen-science data. It is the 306th most-seen of the 428 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.
July
In that month about 10% of wildlife watchers report a Pale-Marked Angle in Seattle on a given day, against under 5% in August to June, the lowest months. That is one of Seattle's driest months, with about 20 mm of rain against 190 mm in November.
Between 5 and 8 am
Across all the parks we cover, that three-hour window holds the most Pale-Marked Angle sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is most active around dawn and dusk.
Among the best
Of the 3 cities where we can rate Pale-Marked Angle sightings, Seattle ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Portland (United States, under 5%).
GBIF citizen-science records
It is estimated from how often the Pale-Marked Angle is recorded against all the insects logged in Seattle (10 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.
