Rare
Under 5% of wildlife watchers report a Redcurrant Blister Aphid sighting in London on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 1300th most-seen of the 1504 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Redcurrant Blister Aphid in London on a given day, so our monthly data shows no clear season.
Among the best
Of the 3 cities where we can rate Redcurrant Blister Aphid sightings, London ranks 3rd at under 5%, level with the leaders once rounded. The best odds are in Berlin (Germany, under 5%) and Vienna (Austria, under 5%).
Same family: Aphididae
The closest relatives of the Redcurrant Blister Aphid that you can see in London (family Aphididae, Aphids) are Giant Willow Aphid (about 10%), Elm Balloon-Gall Aphid (about 10%) and Elm Sack Gall Aphid (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Redcurrant Blister Aphid is recorded against all the insects logged in London (6 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.
