With luck
About 10% of wildlife watchers report a Deduced Graphic sighting in Mesa on a given day, based on 31 verified sightings from GBIF citizen-science data. It is the 68th most-seen of the 232 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
In that month about 20% of wildlife watchers report a Deduced Graphic in Mesa on a given day, against under 5% in October to March, the lowest months. That is one of Mesa's driest months, with about 5 mm of rain against 35 mm in January.
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.
Yes
Of the 8 cities where we can rate Deduced Graphic sightings, Mesa has the highest daily chance: about 10%. Next come 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 Mesa (family Erebidae, Underwing, Tiger, Tussock, and Allied Moths) are Merry Graphic Moth (about 10%), Anvil-Wing Moth (about 10%) and Bird Toxonprucha (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 Mesa (31 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.
