Rare
Under 5% of wildlife watchers report a Green Drab sighting in Brisbane on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 981st most-seen of the 1083 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Green Drab in Brisbane on a given day, so our monthly data shows no clear season.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Green Drab sightings with a recorded time, and about half of them come between 6 am and 6 pm: it is most active around dawn and dusk.
6th of 6
Of the 6 cities where we can rate Green Drab sightings, Brisbane ranks 6th at under 5%. The best odds are in Tel Aviv (Israel, about 10%), Perth (Australia, about 10%) and Johannesburg (South Africa, under 5%).
GBIF citizen-science records
It is estimated from how often the Green Drab is recorded against all the insects logged in Brisbane (5 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.
