65 Caterpillars

During a walk up Leviticus Hill, I stumbled across a working line of 65 caterpillars. They made their way across the concrete in a perfect chain that did not break even once.
 After some research when I returned to Wales, I discovered this species is known as Pine Processionary. They live in large tents, usually in Pine Trees, and march out at night in single file to feed along pine trees in their single filed manner. The caterpillars I came across were out close to mid day, which according to online research, indicates they were now fully grown and in search of pupation sites. A spectacular event I hope to catch more and more throughout my life.
