Possible
About 30% of wildlife watchers report an Ithra Crescent sighting in El Palmar National Park on a given day, based on 16 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 10th most-seen of the 35 insects we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
September
In that month about 60% of wildlife watchers report an Ithra Crescent in El Palmar National Park on a given day, against under 5% in June–August, October and December, the lowest months.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Ithra Crescent sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 4 parks where we can rate Ithra Crescent sightings, El Palmar National Park ranks 2nd at about 30%, level with the leaders once rounded. The best odds are in Iguazú National Park (Argentina, about 30%).
GBIF citizen-science records
It is estimated from how often the Ithra Crescent is recorded against all the insects logged in El Palmar National Park (16 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.
