With luck
About 10% of wildlife watchers report a Tissue Moth sighting in Seattle on a given day, based on 161 verified sightings from GBIF citizen-science data. It is the 34th 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 50%, if each day is a fresh chance.
August and September
In those months about 20% of wildlife watchers report a Tissue Moth in Seattle on a given day, against under 5% in January–February and June, the lowest months. Those are among Seattle's driest months, with about 45 mm of rain a month against 190 mm in November.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Tissue Moth 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 4 cities where we can rate Tissue Moth sightings, Seattle has the highest daily chance: about 10%. Next come Portland (United States, about 10%) and Vancouver (Canada, under 5%).
Same family: Geometridae
The closest relatives of the Tissue Moth that you can see in Seattle (family Geometridae, Geometer Moths) are Omnivorous Looper (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 Tissue Moth is recorded against all the insects logged in Seattle (161 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.
