Rare
Under 5% of wildlife watchers report a Phymatodes grandis sighting in Sacramento on a given day, based on 10 verified sightings from GBIF citizen-science data. It is the 238th most-seen of the 386 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.
April and May
In those months about 10% of wildlife watchers report a Phymatodes grandis in Sacramento on a given day, against under 5% in June to March, the lowest months.
Only Sacramento, in our data
Sacramento is the only city on Wallace's Line with enough records to rate Phymatodes grandis sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Phymatodes grandis is recorded against all the insects logged in Sacramento (10 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.
