Caption
Timelapse of Lesser Willow Sawfly (Nematus pavidus) larvae consuming a Goat Willow (Salix caprea) leaf, meanwhile, another batch of sawfly eggs on the underside of the leaf hatch, and the small larvae start to compete with their larger bretheren. After 44 hours, the leaf is mostly 'skeletonised' and the larvae have moved on to find other leaves
