With luck
About 10% of wildlife watchers report a Texas Mermiria sighting in Big Bend National Park on a given day, based on 18 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 96th most-seen of the 329 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
September
In that month about 40% of wildlife watchers report a Texas Mermiria in Big Bend National Park on a given day, against under 5% in December to June, the lowest months. That is one of Big Bend National Park's wettest months, with about 50 mm of rain against 10 mm in April.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Texas Mermiria sightings with a recorded time, and about 8 in 10 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 Texas Mermiria sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Texas Mermiria is recorded against all the insects logged in Big Bend National Park (18 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.
