This is Calosoma scrutator. This is our largest and probably most attractive Calosoma. These beetles are commonly known as "caterpillar hunters". They are fast and ferocious predators of the night. Where present, this species can be quite common at times (even in daylight) actively foraging for food or mates. They are readily attracted to Mercury Vapor lights but, other light sources will also draw them in lesser numbers.
Although, these beneficial beetles are specialists of caterpillar predation; they will readily seize anything they feel they can overpower. These beetles can "nip" with their short but, strong mandibles however, more often than not they simple spray an offending bother with a smelly acrid (foul smelling) spray from their abdomen.
I recall well a particular occasion when I came across an outbreak of inchworm caterpillars on a medium sized tree at a local forest preserve. These caterpillars were walking all about the bark, tree branches, and leaves of this tree whilst others dangled by threads in the wind. And sure enough in broad daylight I sighted at least 30 of these such beetles clambering about feasting on inchworms one after the other.
