Possible
About 30% of wildlife watchers report a Somena scintillans sighting in Taroko National Park on a given day, based on 75 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 19th most-seen of the 447 insects we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.
March
In that month about 50% of wildlife watchers report a Somena scintillans in Taroko National Park on a given day, against under 5% in September, the lowest month.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Somena scintillans sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Only Taroko National Park, in our data
Taroko National Park is the only park on Wallace's Line with enough records to rate Somena scintillans sightings: about 30% of wildlife watchers there report one on a given day.
Same family: Erebidae
The closest relatives of the Somena scintillans that you can see in Taroko National Park (family Erebidae, Underwing, Tiger, Tussock, and Allied Moths) are Cocoa Tussock Moth (about 60%), Taiwan Yellow Tussock Moth (about 50%) and Chrysaeglia magnifica (about 40%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Somena scintillans is recorded against all the insects logged in Taroko National Park (75 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.
