What's in a name?


Among the few moths caught last night this rather early Cinnabar. Artists or chemists may know the origin of its name (but I had to look it up in Wikipedia): cinnabar is the red form of mercury sulphide – an historic source of the scarlet pigment known as vermilion (or vermillion) used in art works since antiquity. While the rock may not look a good match for the colour of the moth, the pigment is.
