Rare
Under 5% of wildlife watchers report a Yellow Palm Dart sighting in Brisbane on a given day, based on 29 verified sightings from GBIF citizen-science data. It is the 385th 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 30%, if each day is a fresh chance.
February–April and June
In those months about 10% of wildlife watchers report a Yellow Palm Dart in Brisbane on a given day, against under 5% in May and July–January, the lowest months.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Yellow Palm Dart sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 3
Of the 3 cities where we can rate Yellow Palm Dart sightings, Brisbane ranks 3rd at under 5%. The best odds are in Singapore (Singapore, about 10%) and Kuala Lumpur (Malaysia, about 10%).
GBIF citizen-science records
It is estimated from how often the Yellow Palm Dart is recorded against all the insects logged in Brisbane (29 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.
