I'm surprised by the author's description of this insect's smell as "rotten almond-like", as I have routinely run into these stinkbugs for years, and have always found that the odor they emit is EXACTLY like cilantro!  In fact, I have collected 12 or 15 of them a couple of times, ground them up in a mortar, and used the resulting paste as a substitute for cilantro in guacamole!  Nobody could tell the difference.  This might sound rather gross to the average person, but a very similar and closely related insect is widely consumed and eaten in south-central Mexico (that one is more minty-herbal in flavor).
