With luck
About 10% of wildlife watchers report a Dialithis gemmifera sighting in Corcovado National Park on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 77th most-seen of the 116 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
February
In that month about 20% of wildlife watchers report a Dialithis gemmifera in Corcovado National Park on a given day, against under 5% in April to January, the lowest months. That is one of Corcovado National Park's driest months, with about 65 mm of rain against 770 mm in October.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Dialithis gemmifera 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 Corcovado National Park, in our data
Corcovado National Park is the only park on Wallace's Line with enough records to rate Dialithis gemmifera sightings: about 10% of wildlife watchers there report one on a given day.

GBIF citizen-science records
It is estimated from how often the Dialithis gemmifera is recorded against all the insects logged in Corcovado National Park (6 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.
