Rare
Under 5% of wildlife watchers report a Vancouver Dart sighting in Vancouver on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 328th most-seen of the 482 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Vancouver Dart 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 Vancouver Dart sightings with a recorded time, and about half of them come between 6 pm and 6 am: it is most active around dawn and dusk.
Among the best
Of the 2 cities where we can rate Vancouver Dart sightings, Vancouver ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Portland (United States, under 5%).
Same family: Noctuidae
The closest relatives of the Vancouver Dart 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 Vancouver Dart is recorded against all the insects logged in Vancouver (9 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.
