The Hissing Beetle

The other night I was picking up around the bathroom, which unfortunately doubles as a hallway into the backyard and is thus a local favorite with any of the numerous nasty flying things that are attracted to light, when I discovered a curiously large, greenish beetle hiding beneath some dirty clothing. Gingerly, I approached it with some scraps of cardboard, intending to release it back into the wild when it reared back on its hind legs and emitted a hissing sound "Kee! Kee! Kee!" (you can make this sound by touching your tongue to the bottom of your mouth and forcing air through it). With each hiss ("Kee! Kee! Kee!"), it rocked its body menacingly. Holy fuck! Needless to say, I jumped up and apparently made enough noise to send my room mate running towards the bathroom, fully expecting to have to pull a steak knife out of my body me or face some other similarly tragic ordeal. Thankfully, she captured and released the demon-bug while I cowered in another room. Alas, I have no photos, so identifying the vile pest has been challenging.
