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 →

Rare
Under 5% of wildlife watchers report an Omnivorous Looper sighting in San Diego on a given day, based on 70 verified sightings from GBIF citizen-science data. It is the 127th most-seen of the 693 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.
May and July
In those months about 10% of wildlife watchers report an Omnivorous Looper in San Diego on a given day, against under 5% in June and August–April, the lowest months. Those are among San Diego's driest months, with about 5 mm of rain a month against 55 mm in February.
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.
4th of 5
Of the 5 cities where we can rate Omnivorous Looper sightings, San Diego ranks 4th at under 5%. The best odds are in Seattle (United States, about 10%), 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 San Diego (family Geometridae, Geometer Moths) are Dwarf Tawny Wave (about 10%) and Somber Carpet Moth (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 San Diego (70 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.
