Macrosiphum albifrons
In 3 days ~20% in a week ~30%
Macrosiphum albifrons, the lupin aphid, is a species of large grey/ green aphid in the family Aphididae. It is a species native to North America which was first reported in the UK in 1981 where it now occurs widely. Infestations cause lupin plants to wilt and collapse. This may be because the aphid has no natural predators in the UK and populations can grow unchecked. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Lupine Aphid is recorded against all the insects logged in Liverpool (10 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.
