skittering

Skittering is a term describing rapid, light, and irregular movement of a creature or person, characterized by quick, short steps or hops. It is often used to describe small animals, such as insects, spiders, and small vertebrates, moving along surfaces with low mass and high acceleration relative to body size. The term can also describe human motion that is quick, jittery, or evasive.

Biomechanics: Skittering typically involves brief contact of the feet with the surface, with drafts of air or surface irregularities causing erratic paths. In arthropods, multiple legs provide alternating support phases, enabling rapid change of direction with minimal propulsion. On smooth surfaces, traction is crisp; on cluttered terrain, leg coordination increases. It is distinct from scurrying (rapid, more purposeful) and from creeping (slow, continuous).

Etymology: The verb skitter is onomatopoeic and likely originated as an imitative word in English, reflecting the sound or feel of rapid light steps. The form 'skittering' appears in English from the 16th-17th centuries, with later usage in natural history and everyday language.

In culture and usage: In fiction and reportage, skittering is used to evoke a sense of unease or quick movement. It often appears in natural history descriptions and field guides as a neutral descriptor for small, quick-bodied animals. The term is also used in various scientific and hobbyist contexts to describe motion patterns that are too brisk for a crawl but not as uniform as sprinting.
