In 3 days ~10% in a week ~20%
The garden dart (Euxoa nigricans) is a moth of the family Noctuidae. It is distributed throughout much of the Palearctic. Temperate regions of Europe, Central Asia and North Asia, as well as the mountains of North Africa. Absent from polar regions, on Iceland and some Mediterranean islands (Balearic Islands, Malta, Greek Islands, Crete, Cyprus), as well as in Macaronesia (Azores, Madeira, Canary Islands).
This is a rather drab species, forewings ranging from pale to dark brown with indistinct markings. The hindwings are white with a grey fringe. The wingspan is 32–40 mm. This moth flies at night in July and August [1] and is attracted to light and many different flowers.
Forewing black brown with all markings obscured, or dark red-brown with the markings plainer; the edges of stigmata finely black; some ochreous scales on outside of reniform, along the course of submarginal line and at base below cell; hindwing brownish fuscous, the basal half paler in male. More than 20 aberrations are noted by Tutt, grouped, as usual, according to colouration; — the first two, with ground colour grey, are rare: -ab. pallida Tutt with a reddish tinge, and... Wikipedia →

Rare
Under 5% of wildlife watchers report a Garden Dart sighting in London on a given day, based on 14 verified sightings from GBIF citizen-science data. It is the 895th most-seen of the 1504 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.
August
In that month about 10% of wildlife watchers report a Garden Dart in London on a given day, against under 5% in September to July, the lowest months.
Yes
Of the 2 cities where we can rate Garden Dart sightings, London has the highest daily chance: under 5%. Next come Moscow (Russia, under 5%).
Same family: Noctuidae
The closest relatives of the Garden Dart that you can see in London (family Noctuidae, Cutworm Moths and Allies) are Large Yellow Underwing (about 30%), Heart And Dart (about 20%) and Shuttle-Shaped Dart (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Garden Dart is recorded against all the insects logged in London (14 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.
