Stenoma byssina
In 3 days ~10% in a week ~30%
Stenoma byssina is a moth of the family Depressariidae. It is found in Brazil (Amazonas), Venezuela, French Guiana, Guyana, Trinidad and Paraguay. The wingspan is 20–30 mm. The forewings are pale green with a faint grey dot at the end of the cell and two triangular fuscous spots on the costa, one at midpoint and one at the apical three-fourths. From the latter extends an outwardly curved transverse line of grey spots to the dorsum before the tornus. The dorsum is edged with grey and there is a grey spot in the fold surrounded with irregular grey suffusion. The hindwings are pale yellow, more or less heavily overcast with grey in the anal area.
The larvae feed on the foliage of Melicocca bijuga. Wikipedia →

Rare
Under 5% of wildlife watchers report a Stenoma byssina sighting in Monteverde Cloud Forest Reserve on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 412th most-seen of the 506 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.
March, May–June and September
In those months about 10% of wildlife watchers report a Stenoma byssina in Monteverde Cloud Forest Reserve on a given day, against under 5% in April, July–August and October–February, the lowest months.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Stenoma byssina sightings with a recorded time, and nearly all of them come between 6 pm and 6 am: it is mostly seen at night.
Only Monteverde Cloud Forest Reserve, in our data
Monteverde Cloud Forest Reserve is the only park on Wallace's Line with enough records to rate Stenoma byssina sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Stenoma byssina is recorded against all the insects logged in Monteverde Cloud Forest Reserve (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.
