Under the skin
The hidden panic over collembola.
The collembola, known to most as springtails, are a group of invertebrates very closely related to the insects. They are tiny, inconspicuous, and innumerable. Every patch of soil you step on is almost bound to contain thousands of these tiny creatures. They feed mostly on detritus, bacteria, fungi, and algae and congregate in moist areas with lots of organic matter.
