Phalangium opilio. (Arachnida: Opiliones, Phalangiidae) Harvestman, Daddy longlegs, Harvest spider. Of the many species of harvestmen known, P. opilio tends to be the most common in relatively disturbed habitats such as most crops in temperate regions. Like the spiders and most adult mites, harvestmen have two major body sections and eight legs ...

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...

About. The Common harvestman is familiar to us as the long-legged, small-bodied spider-like creature that frequents gardens and houses. Harvestmen are a common and widespread group of long-legged invertebrates and about 25 species live in the UK. They are arachnids, related to spiders and scorpions. Many are predators, eating smaller ...

Aug 4, 2021 · Developmental transcriptomes of the emerging model species Phalangium opilio have suggested that harvestmen do not exhibit systemic genome duplication, as evidenced by the absence of paralogy across the homeobox gene family [2,14] and gene expression patterns of genes with known paralogues in arachnopulmonates [2,6].
Feb 1, 2005 · Abstract. The harvestman Phalangium opilio L. is an abundant predator in an array of habitats, including agricultural systems. In these systems, P. opilio has been noted to feed on pest species (e.g., Colorado potato beetle larvae, various aphid species, and lepidopteran eggs).
