With luck
About 10% of wildlife watchers report a Hyalurga fenestra sighting in Cahuita National Park on a given day, based on 7 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 25th most-seen of the 51 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
November to January
In those months about 20% of wildlife watchers report a Hyalurga fenestra in Cahuita National Park on a given day, against under 5% in February–July and September–October, the lowest months.
Between 5 and 8 pm
Across all the parks we cover, that three-hour window holds the most Hyalurga fenestra sightings with a recorded time, and about 7 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Only Cahuita National Park, in our data
Cahuita National Park is the only park on Wallace's Line with enough records to rate Hyalurga fenestra sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Hyalurga fenestra is recorded against all the insects logged in Cahuita National Park (7 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.
