Family Phalangiidae

Body length 4-6 mm.

The female is larger than the male, and has a dark saddle which widens to a truncated back edge, giving it a characteristic triangular shape. Males and females normally have pale eye rings around the dark eyes, separated by a darker mid-line. Similar to Leiobunum rotundum, but distinguished by having dark eye rings.

Seen May to November, peaking in September.

It feeds on a wide range of invertebrates including insects, worms, snails and slugs, and even other harvestmen.

Found mainly in woodland, but also in gardens and parks. Widespread and fairly common in most of England and Wales, but scarcer further north. Native to the British Isles.
