With luck
About 10% of wildlife watchers report an Arachnis citra sighting in Zion National Park on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 91st most-seen of the 114 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
April to July
In those months about 10% of wildlife watchers report an Arachnis citra in Zion National Park on a given day, against under 5% in August to March, the lowest months. Those are among Zion National Park's driest months, with about 20 mm of rain a month against 75 mm in March.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Arachnis citra sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is seen both by day and at night.
Only Zion National Park, in our data
Zion National Park is the only park on Wallace's Line with enough records to rate Arachnis citra sightings: about 10% of wildlife watchers there report one on a given day.
Same family: Erebidae
The closest relatives of the Arachnis citra that you can see in Zion National Park (family Erebidae, Underwing, Tiger, Tussock, and Allied Moths) are Edwards' Glassy-Wing (about 10%), Litocala Moth (about 10%) and Box-Elder Tussock Moth (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Arachnis citra is recorded against all the insects logged in Zion National Park (5 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.
