With luck
About 10% of wildlife watchers report a Ruddy Daggerwing sighting in Sian Ka'an Biosphere Reserve on a given day, based on 8 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 9th most-seen of the 20 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 60%, if each day is a fresh chance.
June and December
In those months about 30% of wildlife watchers report a Ruddy Daggerwing in Sian Ka'an Biosphere Reserve on a given day, against under 5% in January–April and July–October, the lowest months. Those are among Sian Ka'an Biosphere Reserve's wettest months, with about 150 mm of rain a month against 30 mm in March.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Ruddy Daggerwing sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
11th of 25
Of the 25 parks where we can rate Ruddy Daggerwing sightings, Sian Ka'an Biosphere Reserve ranks 11th at about 10%. The best odds are in Iguazú National Park (Argentina, about 20%), Cuyabeno Wildlife Reserve (Ecuador, about 20%) and Iguaçu National Park (Brazil, about 20%).
GBIF citizen-science records
It is estimated from how often the Ruddy Daggerwing is recorded against all the insects logged in Sian Ka'an Biosphere Reserve (8 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.
