Junonia nigrosuffusa
In 3 days ~20% in a week ~30%
Junonia nigrosuffusa, the dark buckeye, is a species in the butterfly family Nymphalidae. It is found in the southwestern United States and Mexico. Junonia nigrosuffusa and Junonia zonalis were formerly subspecies of Junonia evarete, the tropical buckeye, but were elevated to the species rank as a result of phylogenetic and DNA research. As a result, the geographic range of Junonia evarete is limited primarily to South America. Wikipedia →

With luck
About 10% of wildlife watchers report a Dark Buckeye sighting in Saguaro National Park on a given day, based on 13 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 157th most-seen of the 354 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.
April, June, September and November–January
In those months about 10% of wildlife watchers report a Dark Buckeye in Saguaro National Park on a given day, against under 5% in February–March, May, July–August and October, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Dark Buckeye sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Only Saguaro National Park, in our data
Saguaro National Park is the only park on Wallace's Line with enough records to rate Dark Buckeye sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Dark Buckeye is recorded against all the insects logged in Saguaro National Park (13 verified sightings from 2019 to 2026), 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.
