Sabulodes aegrotata, the Omnivorous Looper, is a moth of the family Geometridae. It is found in Western North America, from British Columbia to California. The larvae eat a wide variety of flowering trees and plants including some agricultural crops. Its distinguishing feature is that the medial and postmedial lines intersect near the trailing edge of the wing.
This moth is common in damp coastal forests along the west coast of North America from British Columbia to California. This species has three generations per year in coastal areas and four or five generations in inland locations. Depending on temperature, egg-to-adult development takes 2 to 5 months.
Eggs are barrel-shaped, light green to reddish brown with a ring of tiny projections. Eggs are laid in clusters on leaves of the host plants and hatch after 8 or 9 days. When mature caterpillars are ready to pupate, they make pearly white to brown cocoons, hidden in between leaves. Pupation lasts 1 to 4 weeks.
The larva make shelters from silk and folded leaves where they shelter during the day and come out at night to feed. The University of California IPM Program gives a description of... Wikipedia →

With luck
About 10% of wildlife watchers report an Omnivorous Looper sighting in Seattle on a given day, based on 145 verified sightings from GBIF citizen-science data. It is the 44th most-seen of the 428 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
April–May and July–November
In those months about 10% of wildlife watchers report an Omnivorous Looper in Seattle on a given day, against under 5% in June and December–March, the lowest months.
Between 9 pm and midnight
Across all the parks we cover, that three-hour window holds the most Omnivorous Looper sightings with a recorded time, and about half of them come between 6 pm and 6 am: it is seen both by day and at night.
Yes
Of the 5 cities where we can rate Omnivorous Looper sightings, Seattle has the highest daily chance: about 10%. Next come San Francisco (United States, about 10%) and Portland (United States, about 10%).
Same family: Geometridae
The closest relatives of the Omnivorous Looper that you can see in Seattle (family Geometridae, Geometer Moths) are Tissue Moth (about 10%), Small Dusty Wave (about 10%) and Brown-Lined Looper (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Omnivorous Looper is recorded against all the insects logged in Seattle (145 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.
