Rare
Under 5% of wildlife watchers report an Elm Balloon-Gall Aphid sighting in Vienna on a given day, based on 12 verified sightings from GBIF citizen-science data. It is the 795th 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.
February and December
In those months about 10% of wildlife watchers report an Elm Balloon-Gall Aphid in Vienna on a given day, against under 5% in January and March–November, the lowest months.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Elm Balloon-Gall Aphid sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 2
Of the 2 cities where we can rate Elm Balloon-Gall Aphid sightings, Vienna ranks 2nd at under 5%. The best odds are in London (United Kingdom, about 10%).
GBIF citizen-science records
It is estimated from how often the Elm Balloon-Gall Aphid is recorded against all the insects logged in Vienna (12 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.
