Rare
Under 5% of wildlife watchers report an Ethmia hammella 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.
February–March, August and November
In those months about 10% of wildlife watchers report an Ethmia hammella in Monteverde Cloud Forest Reserve on a given day, against under 5% in April–July, September–October and December–January, the lowest months.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Ethmia hammella sightings with a recorded time, and about 8 in 10 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 Ethmia hammella sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Ethmia hammella 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.
