There comes to mind, the passage from Bill Bryson's book about his travels in Australia: involving a visit to a national park in a remote high-altitude part of the state of Victoria, and conversation with a warden there concerning the bogong moth, reckoned something of a delicacy by Native Australians -- who roast it in hot ashes and eat it whole. Bryson asks the warden whether he has ever eaten one. The reply is, "once -- once was enough". Asked "what did it taste like?", the answer is, "Like a moth".
Bryson: "I read that it has a kind of buttery taste."
Warden: "No. It has a moth taste."
