With luck
About 10% of wildlife watchers report a Yellow Palm Dart sighting in Daintree National Park on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 745th most-seen of the 856 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.
March, May and July–August
In those months about 10% of wildlife watchers report a Yellow Palm Dart in Daintree National Park on a given day, against under 5% in April, June and September–February, 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.
Only Daintree National Park, in our data
Daintree National Park is the only park on Wallace's Line with enough records to rate Yellow Palm Dart sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Yellow Palm Dart is recorded against all the insects logged in Daintree National Park (5 verified sightings from 2019 to 2026), 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.
