Rare
Under 5% of wildlife watchers report a Walnut Aphid sighting in Berlin on a given day, based on 17 verified sightings from GBIF citizen-science data. It is the 497th most-seen of the 1065 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
June and October
In those months about 10% of wildlife watchers report a Walnut Aphid in Berlin on a given day, against under 5% in July–September and November–May, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Walnut Aphid 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 5 cities where we can rate Walnut Aphid sightings, Berlin ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Kyiv (Ukraine, under 5%).
Same family: Aphididae
The closest relatives of the Walnut Aphid that you can see in Berlin (family Aphididae, Aphids) are Lime Leaf Aphid (about 10%) and Poplar Spiral Gall Aphid (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Walnut Aphid is recorded against all the insects logged in Berlin (17 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.
