Length 2 mm.

Barely visible to the naked eye, this springtail has distinctive purplish markings on its back, especially the crucial broken “U” on the large 4th abdominal segment, and the continuous “W” on the same segment, which helps to identify it compared to other similar species; but length of abdominal segments also need to be taken into account. Similar to E. nivalis, although there seems some disagreement amongst the experts whether E. intermedia and E. nivalis  are one and the same species but with variations in the markings.

Seen all year round, it feeds on leaf-litter and other dead plant matter. Found in various habitats, living in leaf-litter and other plant detritus. Common and widespread throughout Great Britain.
