  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 · We assembled the first harvestman draft genome for the species Phalangium opilio, which bears elongate, prehensile appendages, made possible by numerous distal articles called tarsomeres. Here, we show that the genome of P. opilio exhibits a single Hox cluster and no evidence of WGD.

  4. 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]

  5. 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 ...

  6. 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).

  7. 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.

  8. Aug 7, 2021 · Through a process known as RNA interference (RNAi), scientists have been able to modify the genetic make-up of the daddy long-legs arachnid so that its distinctive spindly limbs become twice as short. This process – which uses a gene's own DNA sequence and small fragments of RNA to turn the gene off – was applied to the Phalangium opilio ...
