Rare
Under 5% of wildlife watchers report a Pale-Marked Angle sighting in Vancouver on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 439th most-seen of the 482 insects we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Pale-Marked Angle in Vancouver on a given day, so our monthly data shows no clear season.
Between 5 and 8 am
Across all the parks we cover, that three-hour window holds the most Pale-Marked Angle sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is most active around dawn and dusk.
Among the best
Of the 3 cities where we can rate Pale-Marked Angle sightings, Vancouver ranks 3rd at under 5%, level with the leaders once rounded. The best odds are in Portland (United States, under 5%) and Seattle (United States, under 5%).
GBIF citizen-science records
It is estimated from how often the Pale-Marked Angle is recorded against all the insects logged in Vancouver (5 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.
