To travel by sand fly is to travel by a somewhat unreliable method. Following the example of the local inhabitants we merely wait for one to turn up in our vicinity. Thankfully, this occurs with a high frequency, but one never knows quite when to expect them, and so we must be constantly prepared to disembark with alacrity. Instead of a boarding bridge we use a rather narrow corridor to enter the first reception area of the sand fly. Quite incredible that we should pass through its head, and then to be sluiced through and into the opulent surroundings of the gut. Unfolding that most exquisite invention the ‘flagella’ to swim, we adapted to the new circumstances.
