Rare
Under 5% of wildlife watchers report a Theona Checkerspot sighting in Monterrey on a given day, based on 13 verified sightings from GBIF citizen-science data. It is the 230th most-seen of the 413 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
May and September
In those months about 10% of wildlife watchers report a Theona Checkerspot in Monterrey on a given day, against under 5% in June–August and October–April, the lowest months. Those are among Monterrey's wettest months, with about 130 mm of rain a month against 20 mm in February.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Theona Checkerspot sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
4th of 5
Of the 5 cities where we can rate Theona Checkerspot sightings, Monterrey ranks 4th at under 5%. The best odds are in Managua (Nicaragua, about 20%), San Pedro Sula (Honduras, about 10%) and San Antonio (United States, under 5%).
Same family: Nymphalidae
The closest relatives of the Theona Checkerspot that you can see in Monterrey (family Nymphalidae, Brush-footed Butterflies) are Monarch (about 30%), American Snout (about 20%) and Bordered Patch (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Theona Checkerspot is recorded against all the insects logged in Monterrey (13 verified sightings), 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.
