The best known is Phalangium opilio . Dicranopalpus ramosus is an invasive species in Europe. It is not to be confused with the harvestman family Phalangodidae, which belongs to the suborder Laniatores.

Members of the order Opiliones (Arachnida) are omnivorous, but their diet consists primarily of small, soft-bodied organisms (Sankey and Savory 1974). As predators, primarily at night, harvestmen consume other harvestmen, gastropods, small earthworms, millipedes, spiders, mites, earwigs, flies, springtails, aphids, leafhoppers, and additional types...
Laboratory colonies of both H. zea and A. glycines were maintained at the University of Kentucky for each experiment. H. zea was maintained using methods similar to those of Ignoffo (1965). A colony of A. glycineswas kept on soybean in a greenhouse at 16:8 (L:D) and 24–30°C. The amount of prey provided always exceeded the predator's daily consumpti...
Several factors affect the development and reproduction of predators, including the quality and complexity of diet. Some predators may incur low survival, long developmental periods, and lower fecundity when they feed on low-quality prey (Toft and Wise 1999). Toft (1995) found that the linyphiid spider Erigone atra (Blackwall) had increased reprodu...

Members of this family have a well developed marsupium that opens anteriorly. They usually give birth to a single young per litter. They are omnivores, foraging nocturnally or around dawn and dusk.

Feb 1, 2005 · We compared the effects of two diets, Helicoverpa zea (Boddie) eggs and Aphis glycines Matsumura, on development of P. opilio because this predator is known to feed on those prey in soybean agroecosystems.

Diet. P. opilio is a generalist predator and scavenger that feeds on soft-bodied animals found in crops, such as aphids, caterpillars, leafhoppers, beetle larvae, and mites. Sometimes it may also scavenge on hard-bodied animals, such as various arthropods, including other harvestmen.
