With luck
About 10% of wildlife watchers report an Elm Balloon-Gall Aphid sighting in London on a given day, based on 67 verified sightings from GBIF citizen-science data. It is the 390th most-seen of the 1504 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
January–February and April–August
In those months about 10% of wildlife watchers report an Elm Balloon-Gall Aphid in London on a given day, against under 5% in March and September–December, the lowest months.

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.
Yes
Of the 2 cities where we can rate Elm Balloon-Gall Aphid sightings, London has the highest daily chance: about 10%. Next come Vienna (Austria, under 5%).
GBIF citizen-science records
It is estimated from how often the Elm Balloon-Gall Aphid is recorded against all the insects logged in London (67 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.
