We're having some fine weather at the moment, but I can almost guarantee that if I sit down in the garden with a mug of tea, then within a few seconds one of those tiny black kamikaze tea flies will be floating on top.
Or to take another example - while out walking, it is perfectly obvious that kamikaze tea flies follow you until you stop for lunch and pull out the flask of tea. They dive almost as soon as you pour. Or it could be coffee, tea flies don’t seem to know the difference.
A very common experience no doubt, but how did the kamikaze tea fly evolve? What evolutionary niche have they exploited by diving into cups of hot tea?
Creationists have an advantage here, because they may simply claim that God created kamikaze tea flies to puzzle us. My theory is that there is no evolutionary advantage at all. The flies are merely having fun. They lay bets on who can skim the tea without contact. All we see in our tea are the losers.
A Darwin award theory you might call it.
Incidentally, how does one remove a kamikaze tea fly? My method is a quick scoop with the forefinger. The fly sticks to the finger and is easily flicked off into oblivion.
For the upper classes taking tea on the lawn, the butler would do it with a sliver fly-spoon from Asprey. Even more exotic would be a delicate Ming dynasty fly spoon carved from a single sliver of green jade, but that’s another world.
