A couple of months ago, walking the dog on a hill track beyond the cemetery, I nearly walked into a quite hideous nest-like construction, hanging from a pine tree at head level, looking like something from a science fiction film, where a very dark secret is about to be unleashed. Or, less dramatically, like dirty white candy floss. I had no idea what it was.
Last week, on exactly the same stretch of path I nearly trod on a procession of caterpillars, which seemed to follow one another along, the head of one – as far as it is able to discriminate with caterpillars – touching the rear of the the other, in a long chain. Since the caterpillar line was directly beneath where the nest had been, I googled ‘caterpillar chain’ and discovered that I had been witness to an appearance by the pine processionary moth, or Thaumetopoea pityocampa.
Apparently the moth lays its eggs in summer, high in a pine tree; the young caterpillars make their nest for the winter – which I witnessed when it had grown to a considerable size in January. As the weather gets warmer they descend to ground level and form processional chains in order to find a place in the soil to pupate.
I looked out for the caterpillars on my way back along the path half an hour later, but they had gone to ground.
The image of these creatures following one another, as if being led blindly by a single caterpillar who seemed to know the way put me in mind of the story of the blind men of Bram.
Bram is a small commune in the Rousillon, not far from Carcassonne. At the time of the Catholic French crusades against the Cathar heretics, Bram was a Cathar stronghold. It fell to the crusade of Simon de Montfort in 1210. The crusaders saved 100 men from the general slaughter, cropped their noses, cut off their lips, and gouged out their eyes. They left one man with one eye intact, to guide the others. The procession of the blind men of Bram roamed the countryside as far as the fortress at Lastours, apparently as a demonstration of the Crusading army’s Christian clemency.
