Dangerous Days at the Office

OK, I'm trying not to freak out. Pasted below is a description of our now-identified insect intruder (according to Wikipedia):

Lethocerus sp. (aka: "The Toe Biter") found in Florida and Montana

Bugs of the family Belostomatidae are fierce predators which stalk, capture and feed on aquatic crustaceans, fish and amphibians. They often lie motionless at the bottom of a body of water, attached to various objects, where they wait for prey to come near. They then strike, injecting a powerful digestive saliva with their mouthparts, and sucking out the liquefied remains.

Their bite is considered one of the most painful that can be inflicted by any insect; the longer the bug is allowed to inject its saliva, the worse the resulting bite, and as the saliva liquefies muscle tissue, it can in rare instances do permanent damage. Adults cannot breathe under water, and must surface periodically for air. Occasionally when encountered by a larger predator, such as a human, they have been known to "play dead" and emit a fluid from their anus. Due to this they are assumed dead by humans and others species only to later "come alive" with painful results.

Belostomatids show parental care and the eggs of many species are laid on the male's wings and carried until they hatch. Adults fly at night, like many aquatic insects, and are attracted to lights during the breeding season.

We have a theory that it hitched a ride in one of our shipments of Montana Silversmiths jewelry. The only other viable theory is that it hitched a ride in my purse on my way home from Florida last month. As you might imagine, I prefer the former.
