P. opilio is a member of the Eupnoi suborder of Opiliones. Distribution. P. opilio has a mostly Holarctic distribution and is the most widespread harvestman species worldwide, occurring natively in Europe, North and Central Asia, and Asia Minor. The species has been introduced to North America, North Africa and New Zealand from Europe.

Appearance. The most notable features of P. opilio and many other harvestmen are the long, slender legs and short, globular body. Adult body length is approximately 3.5–9 mm, with males generally smaller than females. The upper surface of the body is colored with an indistinct and variable light gray or brown pattern, and the lower surface is ...
Feb 1, 2002 · Abstract. A 2-yr pitfall-trap study was conducted to examine the species composition of the Opiliones and the seasonal age-structure of Phalangium opilio (L.) in central Kentucky soybean, grassland, and alfalfa habitats. Phalangium opilio was the most commonly caught opilionid in all habitats, accounting for >90% of the adult specimens captured ...
