Cerceris fumipennis, the only species of buprestid-hunting Philanthidae occurring in eastern North America, is found throughout the continental United States east of the Rockies, from Texas and Florida north to Maine, Wyoming, and into Canada. The wasps most often nest in open areas of hard-packed sandy soil surrounded by woody habitat suitable for their buprestid beetle prey.
Cerceris fumipennis is distinguished by five conspicuous characteristics: It is large, about the size of common yellow jacket wasps. It has dark smoky, blue/black wings. The wasp's body is predominantly black except for a few yellow markings.
It has a conspicuous, single, broad, creamy yellow abdominal band. Females have three creamy patches between the eyes, while males are marked with two yellow triangles abutting their eyes. Cerceris fumipennis is a solitary, ground-nesting wasp. Each lone female constructs and attempts to maintain a single subterranean nest for the duration of the flight season. Her solitary nest is in close proximity to others, forming a neighborhood or informal colony of nests. The nest's entrance is easily visible, marked by a small, circular mound... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Smoky-Winged Beetle Bandit Wasp is recorded against all the insects logged in Boston (82 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.
