With luck
About 10% of wildlife watchers report a Mythimna decisissima sighting in Daintree National Park on a given day, based on 11 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 402nd 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 50%, if each day is a fresh chance.
August
In that month about 20% of wildlife watchers report a Mythimna decisissima in Daintree National Park on a given day, against under 5% in October to April, the lowest months. That is one of Daintree National Park's driest months, with about 60 mm of rain against 380 mm in January.
Between 6 and 9 pm
Across all the parks we cover, that three-hour window holds the most Mythimna decisissima sightings with a recorded time, and nearly all of them come between 6 pm and 6 am: it is mostly seen at night.
Only Daintree National Park, in our data
Daintree National Park is the only park on Wallace's Line with enough records to rate Mythimna decisissima sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Mythimna decisissima is recorded against all the insects logged in Daintree National Park (11 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.
