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).

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 ...

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 ...
The rapid emergence and utility of Phalangium opilio as a model for evolutionary developmental biology of arthropods serve as demonstrative evidence of a new area of study in Opiliones biology, made possible through transcriptomic data.
Cyphophthalmi. This suborder contains five (or six) families and about 100 species. It is sister to all remaining Opiliones (the “Phalangida”). Cyphophthalmi are eyeless, live in deep moist leaf litter or caves, and range in size from 1 to 7 mm. The animals have a hardened plate covering the entire dorsal surface, and they resemble mites.
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].
Mar 4, 2022 · For these reasons, Phalangium opilio is poised to serve as a linchpin for comparative studies of chelicerate embryology and genomic evolution across Arthropoda. Conclusion The embryonic staging system presented here for the emerging model organism P. opilio brings a fresh perspective to the exceptional classical works on the embryology of ...
