Dense aggregations of Collembola (Hypogastrura nivicola Fitch) move across the surface of the forest floor in central New England in the autumn and spring for distances of 20-25 m before disappearing. Colonies 30 cm in diam have populations of 0.5-1 million individuals. Hourly movement is as much as 75 cm and daily movement as much as 6 m. Overland movement ceases at night or when colonies are covered by black plastic sheeting.
