Trichilogaster acaciaelongifoliae is an Australian bud-galling wasp from the family Melanosomellidae that parasitises, among others, Acacia longifolia (long-leaved wattle, or Sydney golden wattle), which has become an invasive pest in several countries. T. acaciaelongifoliae has been introduced into South Africa in 1985 and into Portugal in 2015 as a successful biological control agent of A. longifolia. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Longleaf Wattle Gall Wasp is recorded against all the insects logged in Porto (28 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.
