Rare
Under 5% of wildlife watchers report a Sweet Potato Weevil sighting in Brisbane on a given day, based on 13 verified sightings from GBIF citizen-science data. It is the 601st 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.
February
In that month about 10% of wildlife watchers report a Sweet Potato Weevil in Brisbane on a given day, against under 5% in March to January, the lowest months. That is one of Brisbane's wettest months, with about 160 mm of rain against 40 mm in July.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Sweet Potato Weevil sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
8th of 12
Of the 12 cities where we can rate Sweet Potato Weevil sightings, Brisbane ranks 8th at under 5%. The best odds are in Fuzhou (China, about 10%), Taichung (Taiwan, about 10%) and Zhuhai [Macau] (China, about 10%).
GBIF citizen-science records
It is estimated from how often the Sweet Potato Weevil is recorded against all the insects logged in Brisbane (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.
