Rare
Under 5% of wildlife watchers report a Greenhouse Thrips sighting in Auckland on a given day, based on 13 verified sightings from GBIF citizen-science data. It is the 370th most-seen of the 689 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.
March and May–July

Of the 3 cities where we can rate Greenhouse Thrips sightings, Auckland has the highest daily chance: under 5%. Next come San Francisco (United States, under 5%) and Los Angeles (United States, under 5%).
GBIF citizen-science records
It is estimated from how often the Greenhouse Thrips is recorded against all the insects logged in Auckland (13 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.
