Collembola are tiny wingless hexapods that jump but lack wings and powered flight. They can build high population densities on the ground. A population may be restricted to a small area bounded by barriers that they cannot cross by jumping. Collembola are still able to move about the planet through the atmosphere. Springtails have been collected from the atmosphere as high as 3350 meters (almost 2 miles). In addition to jumping, collembola can climb trees. Farrow and Greenslade* reported a migration of approximately 500,000 sprintails up the side of a tree, presumably to launch themselves from the treetops into the airstream to be carried downwind.
