Rare
Under 5% of wildlife watchers report a Hop Aphid sighting in Madrid on a given day, based on 12 verified sightings from GBIF citizen-science data. It is the 274th most-seen of the 457 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.
May
In that month about 10% of wildlife watchers report a Hop Aphid in Madrid on a given day, against under 5% in June to April, the lowest months.
Only Madrid, in our data
Madrid is the only city on Wallace's Line with enough records to rate Hop Aphid sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Aphididae
The closest relatives of the Hop Aphid that you can see in Madrid (family Aphididae, Aphids) are Oleander Aphid (about 10%), Rice Root Aphid (about 10%) and Poplar Shoot Aphid (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Hop Aphid is recorded against all the insects logged in Madrid (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.
