Rare
Under 5% of wildlife watchers report an Alpine Dark Bush-Cricket sighting in Vienna on a given day, based on 21 verified sightings from GBIF citizen-science data. It is the 599th 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.
April and June
In those months about 10% of wildlife watchers report an Alpine Dark Bush-Cricket in Vienna on a given day, against under 5% in May and July–March, the lowest months.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Alpine Dark Bush-Cricket 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 Vienna, in our data
Vienna is the only city on Wallace's Line with enough records to rate Alpine Dark Bush-Cricket sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Alpine Dark Bush-Cricket 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.
