Rare
Under 5% of wildlife watchers report a Yellow Angled-Sulphur sighting in Monterrey on a given day, based on 10 verified sightings from GBIF citizen-science data. It is the 262nd 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.
July and September
In those months about 10% of wildlife watchers report a Yellow Angled-Sulphur in Monterrey on a given day, against under 5% in August and October–June, the lowest months. Those are among Monterrey's wettest months, with about 150 mm of rain a month against 20 mm in February.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Yellow Angled-Sulphur sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 4
Of the 4 cities where we can rate Yellow Angled-Sulphur sightings, Monterrey ranks 3rd at under 5%. The best odds are in San Luis Potosí (México, about 10%) and Mexico City (México, under 5%).
GBIF citizen-science records
It is estimated from how often the Yellow Angled-Sulphur is recorded against all the insects logged in Monterrey (10 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.
