Calosoma semilaeve, the black calosoma or semi-smooth beautiful black searcher, is a species of ground beetle in the subfamily Carabinae. It was described by John Lawrence LeConte in 1851. This species is found in Mexico (Baja California) and the United States (Arizona, California, Idaho, Oregon, Utah), where it inhabits cultivated fields and road sides.
Adults are diurnal and nocturnal and prey on caterpillars (including those of Peridroma saucia and Malacosoma incurvum), as well as tenebrionids, elaterids and carabids. Adults overwinter in cavities in the ground. Wikipedia →

Under 5% of wildlife watchers report a Black Calosoma sighting in Los Angeles on a given day, based on 58 verified sightings from GBIF citizen-science data. It is the 229th most-seen of the 851 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.

GBIF citizen-science records
It is estimated from how often the Black Calosoma is recorded against all the insects logged in Los Angeles (58 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.
