Aporophyla lueneburgensis
In 3 days ~10% in a week ~20%
The northern deep-brown dart (Aporophyla lueneburgensis) is a moth of the family Noctuidae. It was first described by Christian Friedrich Freyer in 1848. It is found in northern and western Europe. As the common name suggests, this species usually has very dark brown to purplish grey forewings, although paler grey forms exist. There is always a much darker central band, almost black in the darker forms. All the lines and stigmata are very neatly marked and edged in a paler color. By contrast, the hindwings are much paler, often almost pure white in the male, but usually with darker venation. The wingspan is 36–41 mm. It is a decidedly smaller and neater insect than Aporophyla lutulenta. It flies at night during August and September.[1] It is attracted to light and sugar as well as various flowers.
The larva usually feeds on heather, but has been recorded on other low plants such as bird's-foot trefoil. This species overwinters as a small larva. Wikipedia →

Rare
Under 5% of wildlife watchers report a Northern Deep-Brown Dart sighting in London on a given day, based on 11 verified sightings from GBIF citizen-science data. It is the 1005th 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.
September and October
In those months about 10% of wildlife watchers report a Northern Deep-Brown Dart in London on a given day, against under 5% in November to August, the lowest months.
Only London, in our data
London is the only city on Wallace's Line with enough records to rate Northern Deep-Brown Dart sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Northern Deep-Brown Dart is recorded against all the insects logged in London (11 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.
