With luck
About 10% of wildlife watchers report a Common Anastrus sighting in Iguazú National Park on a given day, based on 11 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 152nd most-seen of the 306 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 50%, if each day is a fresh chance.
May, August–September and December–March
In those months about 10% of wildlife watchers report a Common Anastrus in Iguazú National Park on a given day, against under 5% in April, June–July and October–November, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Common Anastrus 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 2 parks where we can rate Common Anastrus sightings, Iguazú National Park ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Iguaçu National Park (Brazil, about 10%).
Same family: Hesperiidae
The closest relatives of the Common Anastrus that you can see in Iguazú National Park (family Hesperiidae, Skippers) are Common Mylon (about 40%), Aspernatus Skipper (about 20%) and Southern Sicklewing (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Common Anastrus is recorded against all the insects logged in Iguazú National Park (11 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.
