Rare
Under 5% of wildlife watchers report a Common Rustic sighting in Vancouver on a given day, based on 6 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 Common Rustic in Vancouver on a given day, so our monthly data shows no clear season.
Among the best
Of the 3 cities where we can rate Common Rustic sightings, Vancouver ranks 3rd at under 5%, level with the leaders once rounded. The best odds are in London (United Kingdom, under 5%) and Portland (United States, under 5%).
Same family: Noctuidae
The closest relatives of the Common Rustic that you can see in Vancouver (family Noctuidae, Cutworm Moths and Allies) are Large Yellow Underwing (about 10%) and Alfalfa Looper (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Common Rustic is recorded against all the insects logged in Vancouver (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.
