Even at less than 10mm, this “small” ground beetle larva is a huge and powerful predator to the tiny springtail in its jaws. 这种“小”步行虫的幼虫虽然体长不足10毫米,可对于被它擒在颚中的微小的弹尾虫来说,却是雄伟有力的掠食者。
Springtails (Collembola) form the largest of the three lineages of modern hexapods that are no longer considered insects (the other two are the Protura and Diplura). Although the three orders are sometimes grouped together in a class called Entognatha because they have internal mouthparts, they do not appear to be any more closely related to one another than they all are to insects, which have external mouthparts.
