In 3 days ~10% in a week ~30%
Diloba caeruleocephala, the figure of eight, is a moth of the family Noctuidae. It is found in the Palearctic. Diloba caeruleocephala is found in most of Europe except northern Scandinavia, the northern part of the British Isles and the North of
Russia. In the South, it occurs in North Africa, the Middle East (Lebanon, Israel, Jordan), Asia Minor, Iran and Kazakhstan. It is largely missing in Portugal. The wingspan is 30–40 mm. The length of the forewings is 15–19 mm. The heavily combed antennae of the male and the thick, woolly-hairy body of the female is atypical for Noctuidae. The forewings are grey or grey-brown with a purple sheen. The reniform and orbicular stigmata are both in the shape of a figure 8 enclosed in yellowish white. The post median and subterminal lines are black. There is a black tornal streak. The hindwing is an ochreous white. The cilia are greyish brown with a wedge-shaped black tornal mark.
The egg is hemispherical and initially white; later it becomes yellowish and is yellowish brown right before hatching. It has in the fresh state 13 to 16 wide, greenish longitudinal ribs. The larvae are relatively thick at all stages... Wikipedia →

Rare
Under 5% of wildlife watchers report a Figure Of Eight sighting in Vienna on a given day, based on 42 verified sightings from GBIF citizen-science data. It is the 373rd most-seen of the 1406 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
April–May and October
In those months about 10% of wildlife watchers report a Figure Of Eight in Vienna on a given day, against under 5% in June–September and November–March, the lowest months.
Only Vienna, in our data
Vienna is the only city on Wallace's Line with enough records to rate Figure Of Eight sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Noctuidae
The closest relatives of the Figure Of Eight that you can see in Vienna (family Noctuidae, Cutworm Moths and Allies) are Silver Υ (about 20%), Large Yellow Underwing (about 10%) and Cotton Bollworm Moth (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Figure Of Eight is recorded against all the insects logged in Vienna (42 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.
