Rare
Under 5% of wildlife watchers report a Xanthorhoe defensaria sighting in Seattle on a given day, based on 15 verified sightings from GBIF citizen-science data. It is the 232nd most-seen of the 428 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.
September
In that month about 10% of wildlife watchers report a Xanthorhoe defensaria in Seattle on a given day, against under 5% in October to August, the lowest months. That is one of Seattle's driest months, with about 60 mm of rain against 190 mm in November.
Between 9 pm and midnight
Across all the parks we cover, that three-hour window holds the most Xanthorhoe defensaria sightings with a recorded time, and about 7 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
Among the best
Of the 3 cities where we can rate Xanthorhoe defensaria sightings, Seattle ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Portland (United States, under 5%).
GBIF citizen-science records
It is estimated from how often the Xanthorhoe defensaria is recorded against all the insects logged in Seattle (15 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.
