Rare
Under 5% of wildlife watchers report a Blunt-Spined Big-Headed Ant sighting in Saguaro National Park on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 300th most-seen of the 354 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
April and June–July
In those months about 10% of wildlife watchers report a Blunt-Spined Big-Headed Ant in Saguaro National Park on a given day, against under 5% in May and August–March, the lowest months.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Blunt-Spined Big-Headed Ant sightings with a recorded time, and about half of them come between 6 am and 6 pm: it is seen both by day and at night.
Only Saguaro National Park, in our data
Saguaro National Park is the only park on Wallace's Line with enough records to rate Blunt-Spined Big-Headed Ant sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Blunt-Spined Big-Headed Ant is recorded against all the insects logged in Saguaro National Park (6 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.
