The Kumamoto International entomology desk is normally run by William, but seeing this NPR (National Public Radio, a U.S. network) news story prompted me to take a stab at running entomology desk for the day.
I had never hear of a "brown marmorated stink bug" before but the word "stink" made me think of a critter I know from my experience in Japan. When I looked up the scientific name (halyomorpha halys) with some Japanese words (虫, の etc.) I found that, sure enough, the stinky bug I have encountered here seems to be the invasive species identified in the NPR segment. The Japanese name is "kusagi kamemushi." It's usually written in katakana but the kanji are 臭木椿象 -- yup, "stink" is in the Japanese name for this bug too.
It won't kill you but I'd advise you not pick it up. ;)

A Look At Just How Invasive The Brown Marmorated Stink Bug Is
The brown marmorated stink bug first showed up in the United States about 20 years ago, and has been terrorizing homeowners and farmers ever since. NPR's Ari Shapiro talks with Kathryn Schulz, who writes about the invasive insect in the latest issue of The New Yorker.
