Graphiphora augur, the double dart or soothsayer, is a moth of the family Noctuidae. The species was first described by Johan Christian Fabricius in 1775. It is found in all of Canada and most of the northern parts of the United States, south in the west to California and New Mexico. It is also found throughout Eurasia, from the British Isles and Scandinavia to Siberia and Japan.
The wingspan is 35–42 mm. Forewing uniform brownish grey with a reddish tinge; stigmata concolorous, black edged; claviform narrow; orbicular variable, round, or flattened, sometimes prolonged to touch inner line; reniform with outer edge swollen in the middle, sometimes followed by a dark shade: hindwing a little paler. Form hippophaes [Geyer] is a grey form with the reddish tinge wanting; — helvetina Knaggs is a pale blurred form with obscure markings, and the fringe of hindwing pink.
Adults are on wing from June to August depending on the location. There is one generation per year. The larva vary from purplish brown to greenish grey with a double row of whitish spots on the dorsum and oblique dark streaks; a dark brown blotch across segment 12, swollen... Wikipedia →

Rare
Under 5% of wildlife watchers report a Soothsayer Dart sighting in Helsinki on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 509th most-seen of the 838 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.
July
In that month about 10% of wildlife watchers report a Soothsayer Dart in Helsinki on a given day, against under 5% in August to June, the lowest months.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Soothsayer Dart sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Helsinki, in our data
Helsinki is the only city on Wallace's Line with enough records to rate Soothsayer Dart sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Noctuidae
The closest relatives of the Soothsayer Dart that you can see in Helsinki (family Noctuidae, Cutworm Moths and Allies) are Large Yellow Underwing (about 10%), Silver Υ (about 10%) and Antler Moth (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Soothsayer Dart is recorded against all the insects logged in Helsinki (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.
