With luck
About 10% of wildlife watchers report an Oak Lace Bug sighting in Vienna on a given day, based on 141 verified sightings from GBIF citizen-science data. It is the 112th most-seen of the 1406 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 50%, if each day is a fresh chance.
October
In that month about 20% of wildlife watchers report an Oak Lace Bug in Vienna on a given day, against under 5% in June and November–March, the lowest months.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Oak Lace Bug sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 12 cities where we can rate Oak Lace Bug sightings, Vienna ranks 3rd at about 10%, level with the leaders once rounded. The best odds are in Sofia (Bulgaria, about 10%) and Bucharest (Romania, about 10%).
GBIF citizen-science records
It is estimated from how often the Oak Lace Bug is recorded against all the insects logged in Vienna (141 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.
