  1. 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 ...

  2. Aug 4, 2021 · (a) Phalangium opilio draft genome assembly. The draft assembly of the P. opilio genome comprises 580.4 Mbp (37.5% GC content) in 5137 scaffolds (N50: 211 089) and 8349 contigs (N50: 127 429; electronic supplementary material, figure S1 and table S5). The predicted genome repetitiveness is 54.4% and estimated heterozygosity is 1.24%.

  4. Feb 1, 2005 · Phalangium opilio incurred higher mortality, longer developmental periods, and smaller adult body size when fed a monotypic diet of A. glycines. Fecundity also was compromised when fed A. glycines . A mixed diet containing A. glycines caused some adverse effects on reproduction compared with the standard laboratory diet, which did not contain ...

  5. Opiliones are one of the largest arachnid orders, with more than 6,500 species in 50 families. Many of these families have been erected or reorganized in the last few years since the publication of The Biology of Opiliones. Recent years have also seen an explosion in phylogenetic work on Opiliones, as well as in studies using Opiliones as test cases to address biogeographic and evolutionary ...

  6. Mar 14, 2024 · Despite its two-eyed appearance, Phalangium opilio has six peepers. The four extra eyes — leftovers of evolution — shed light on the evolutionary history of daddy longlegs. ljphoto7/iStock ...

  7. 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. [6]

  8. Feb 1, 2005 · 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). Although the potential importance of P. opilio has been recognized, little is known about this harvestman’s development or ...
