With luck
About 10% of wildlife watchers report a Guastica semilutea sighting in Daintree National Park on a given day, based on 10 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.
February
In that month about 30% of wildlife watchers report a Guastica semilutea in Daintree National Park on a given day, against under 5% in March–April and August–November, the lowest months. That is one of Daintree National Park's wettest months, with about 240 mm of rain against 50 mm in September.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Guastica semilutea 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 Guastica semilutea sightings: about 10% of wildlife watchers there report one on a given day.
Same family: Pyralidae
The closest relatives of the Guastica semilutea that you can see in Daintree National Park (family Pyralidae, Pyralid Snout Moths) are Endotricha mesenterialis (about 10%), Lacalma albirufalis (about 10%) and Epicrocis pulchra (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Guastica semilutea is recorded against all the insects logged in Daintree National Park (10 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.
