Steel Blue Cricket Hunter

Dear Kat,
This is not a Beetle.  It is a Steel Blue Cricket Hunter,
Chlorion aerarium, a Wasp in the family Sphecidae.  According to BugGuide:  “Although generally not closely associated with humans, they are found wherever their hosts (Gryllus crickets) are found, which could include close proximity to homes.”  We believe “3+ inches long” is an exaggeration, as BugGuide states:  “~25 mm.”
