An analysis of jumping performance and behavior of the globular springtail Dicyrtomina minuta

Collembola are one of the most common groups of arthropods and among the most spectacular in their ability to jump. However, perhaps due to their small size and extreme speeds, the movements involved in most springtail jumps remain unresolved and undescribed. Using high-speed videography we provide a comprehensive visualization and description of the movements and behaviors involved in the jump of the globular springtail Dicyrtomina minuta. We quantify and visualize: furca release, ground contact and launch times, ballistic trajectory and mid-air rotation, and landing. Comparing unprovoked jumps to jumps in response to a directional stimulus, we find that these globular springtails are only somewhat capable of controlling the direction of takeoff. We also describe two distinct modes of landing: uncontrolled bouncing and rolling, and collophore-assisted arrested landings. Altogether, our work provides a new look at the ultra-fast jumps of these common, but extraordinary arthropods.
