I was walking though some fields in the early spring, about 5 miles east of Famagusta, Cyprus, heading towards a building I was later to write an article on: the Trapeza church (see my articles page on this website). I looked down at one point to see thousands of caterpillars feasting on the new wheat. They were a voracious, writhing mass of colour, devouring the fresh shoots. I wondered what butterflies they were going to become.
