Rare
Under 5% of wildlife watchers report a Pterostichus lama sighting in Portland on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 427th most-seen of the 507 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.
November
In that month about 10% of wildlife watchers report a Pterostichus lama in Portland on a given day, against under 5% in December to October, the lowest months. That is one of Portland's wettest months, with about 220 mm of rain against 10 mm in July.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Pterostichus lama sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 2 cities where we can rate Pterostichus lama sightings, Portland ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Vancouver (Canada, under 5%).
GBIF citizen-science records
It is estimated from how often the Pterostichus lama is recorded against all the insects logged in Portland (6 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.
