Rare
Under 5% of wildlife watchers report a Scarce Blackneck sighting in Vienna on a given day, based on 21 verified sightings from GBIF citizen-science data. It is the 619th 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 20%, if each day is a fresh chance.
August and September
In those months about 10% of wildlife watchers report a Scarce Blackneck in Vienna on a given day, against under 5% in October to July, the lowest months.
Between 11 pm and 2 am
Across all the parks we cover, that three-hour window holds the most Scarce Blackneck sightings with a recorded time, and about 7 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
Only Vienna, in our data
Vienna is the only city on Wallace's Line with enough records to rate Scarce Blackneck sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Erebidae
The closest relatives of the Scarce Blackneck that you can see in Vienna (family Erebidae, Underwing, Tiger, Tussock, and Allied Moths) are Nine-Spotted Moth (about 10%), Four-Spotted Moth (about 10%) and Jersey Tiger (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Scarce Blackneck is recorded against all the insects logged in Vienna (21 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.
