During a visit to Stalin's house in Gori, Georgia I came across these firebugs (Pyrrhocoris apterus), the first time I had ever seen them. Being new to Georgia's flora and fauna I had no idea if they were harmless or poisonous. After a lot of Googling when I got home I was fascinated to learn that researchers had been trying to breed them at Harvard University, only to discover that using the New York Times as bedding led to the bugs dying, whilst the Times Newspaper from Britain was fine. Turns out that the American newspapers were made from Balsam Fir whereas the UK papers were made from conifers. Paper from the balsam fir messed with the bugs' hormones but the conifer based newspaper did not!!
