Rare
Under 5% of wildlife watchers report a Hardya tenuis sighting in Vienna on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 1028th 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.
October
In that month about 10% of wildlife watchers report a Hardya tenuis in Vienna on a given day, against under 5% in November to September, the lowest months.
Only Vienna, in our data
Vienna is the only city on Wallace's Line with enough records to rate Hardya tenuis sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Cicadellidae
The closest relatives of the Hardya tenuis that you can see in Vienna (family Cicadellidae, Typical Leafhoppers) are Zygina nivea (about 10%), Penthimia nigra (about 10%) and Ribautiana debilis (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Hardya tenuis is recorded against all the insects logged in Vienna (8 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.
