Found on the way to the mailbox.
Released an odorous liquid while I was handling it, namely while it was grasped in my fingers. The scent reminded me of citrus and acetone, not particularly offensive or stinky but it was a strong scent.
It only "stinked" me as a last resort, it first attempted running and flying. I made sure to release it outside in the healthy condition I found it in.

Halyomorpha halys, also known as the brown marmorated stink bug (BMSB), or simply the stink bug, is an insect in the family Pentatomidae, and it is native to China, Korea, Japan and Taiwan. It was accidentally introduced into the United States, with the first specimen being collected in September 1998. The brown marmorated stink bug is considered to be an agricultural pest, and by 2010-11 had become a season-long pest in U.S. orchards.
