In many countries there is a type of fly which is born and dies in the same day. It goes by different names and the biology changes around the world, but this type of insect is well known. In England it is called the 'Mayfly', in Germany it is the 'Eintagsfliege'. Down Under, in Australia, it is also called a Mayfly... but it hatches in the late spring and early summer months around November and December.
