This species is found in Mexico (Coahuila, Tamaulipas) and the United States (Arizona, Louisiana, New Mexico, Oklahoma, Texas), where it inhabits mid altitude open areas.
The species is 24–30 millimetres (0.94–1.18 in) long, black, and lives at an elevation of 1,000 to 1,600 metres (3,300 to 5,200 ft). Wikipedia →

Rare
Under 5% of wildlife watchers report a Calosoma macrum sighting in San Antonio on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 581st most-seen of the 697 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Calosoma macrum in San Antonio on a given day, so our monthly data shows no clear season.
Only San Antonio, in our data
San Antonio is the only city on Wallace's Line with enough records to rate Calosoma macrum sightings: under 5% of wildlife watchers there report one on a given day.

GBIF citizen-science records
It is estimated from how often the Calosoma macrum is recorded against all the insects logged in San Antonio (6 verified sightings), 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.
