Thousands of caterpillars were spotted shrouding a tree in webbing in North Yorkshire.<br /><br />The footage, captured on the banks of the River Wharfe near Kilnsey, shows the caterpillars’ silk web covering the trunk and the branches of a tree. <br /><br />The crawling creatures are thought to be ermine moth caterpillars, which form a protective web to protect themselves from predators whilst feeding. <br /><br />The phenomenon can be seen in late spring and beginning of the summer as caterpillars prepare to transform into moths in July and August.
