Dialectica scalariella
In 3 days ~20% in a week ~50%
Dialectica scalariella (echium leaf miner) is a moth of the family Gracillariidae. It is found from France to the Iberian Peninsula, Italy and the Balkan Peninsula. Recently an imago was found in Great Britain. It was introduced in Australia for the biological control of the weed Echium plantagineum and has since spread to New Zealand.
The larvae feed on Anchusa strigosa, Borago, Cynoglossum creticum, Echium aculeatum, Echium giganteum, Echium plantagineum, Echium vulgare, Myosotis latifolia and Symphytum officinale. They mine the leaves of their host plant. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Echium Leaf Miner is recorded against all the insects logged in Auckland (50 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.
