Rare
Under 5% of wildlife watchers report a Deduced Graphic sighting in Phoenix on a given day, based on 18 verified sightings from GBIF citizen-science data. It is the 107th most-seen of the 264 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–June and August–September
In those months about 10% of wildlife watchers report a Deduced Graphic in Phoenix on a given day, against under 5% in July and October–April, the lowest months.
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.
3rd of 8
Of the 8 cities where we can rate Deduced Graphic sightings, Phoenix ranks 3rd at under 5%. The best odds are in Mesa (United States, about 10%) and Torreón (México, about 10%).

The closest relatives of the Deduced Graphic that you can see in Phoenix (family Erebidae, Underwing, Tiger, Tussock, and Allied Moths) are Merry Graphic Moth (about 10%) and Royal Poinciana Graphic (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 Phoenix (18 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.
