With luck
About 10% of wildlife watchers report a Madrone Skin Miner sighting in Seattle on a given day, based on 87 verified sightings from GBIF citizen-science data. It is the 70th 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.
December to May
In those months about 10% of wildlife watchers report a Madrone Skin Miner in Seattle on a given day, against under 5% in June to November, the lowest months.

GBIF citizen-science records
It is estimated from how often the Madrone Skin Miner is recorded against all the insects logged in Seattle (87 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.
