Rare
Under 5% of wildlife watchers report a Madrone Skin Miner sighting in Vancouver on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 350th most-seen of the 482 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Madrone Skin Miner in Vancouver on a given day, so our monthly data shows no clear season.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Madrone Skin Miner sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 3
Of the 3 cities where we can rate Madrone Skin Miner sightings, Vancouver ranks 3rd at under 5%. The best odds are in Seattle (United States, about 10%) and Portland (United States, under 5%).
GBIF citizen-science records
It is estimated from how often the Madrone Skin Miner is recorded against all the insects logged in Vancouver (8 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.
