With luck
About 10% of wildlife watchers report a Mastor eos sighting in Big Bend National Park on a given day, based on 7 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 221st most-seen of the 329 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 and May
In those months about 10% of wildlife watchers report a Mastor eos in Big Bend National Park on a given day, against under 5% in June to March, the lowest months.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Mastor eos sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Only Big Bend National Park, in our data
Big Bend National Park is the only park on Wallace's Line with enough records to rate Mastor eos sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Mastor eos is recorded against all the insects logged in Big Bend National Park (7 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.
