Rare
Under 5% of wildlife watchers report a Deduced Graphic sighting in Monterrey on a given day, based on 12 verified sightings from GBIF citizen-science data. It is the 220th 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 30%, if each day is a fresh chance.
May and September
In those months about 10% of wildlife watchers report a Deduced Graphic 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 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Deduced Graphic sightings with a recorded time, and about 8 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
5th of 8
Of the 8 cities where we can rate Deduced Graphic sightings, Monterrey ranks 5th at under 5%. The best odds are in Mesa (United States, about 10%), Torreón (México, about 10%) and Phoenix (United States, under 5%).
Same family: Erebidae
The closest relatives of the Deduced Graphic that you can see in Monterrey (family Erebidae, Underwing, Tiger, Tussock, and Allied Moths) are Black Witch (about 10%), Eurylomia cordula (about 10%) and Black-Banded Wasp Moth (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Deduced Graphic is recorded against all the insects logged in Monterrey (12 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.
