Feb 22, 2017 · 1. Introduction. Opiliones (‘harvestmen’ or ‘daddy longlegs’) are a remarkable group of arachnids (electronic supplementary material, figure S1), with a fossil record dating to the Early Devonian, having diversified in its main lineages by the Carboniferous [1–3], and showing ancient vicariant patterns that accord with their modern distribution [4–8].

Mar 30, 2024 · Reproduction and Life Cycle. While asexual species do exist, most harvestmen reproduce sexually. Mating typically involves direct copulation, where the males transfer sperm directly to females, which the females store at the tip of their ovipositors and use later for fertilizing their eggs during oviposition.
The Opiliones (formerly Phalangida) are an order of arachnids colloquially known as harvestmen, harvesters, harvest spiders, or daddy longlegs. As of April 2017, over 6,650 species of harvestmen have been discovered worldwide, [1] although the total number of extant species may exceed 10,000. [2] The order Opiliones includes five suborders ...
Phalangium opilio Linnaeus 1758. Size. Adult body ~3.5–3.9 mm, with males generally smaller than females. Identification. Males have a large spur/horn on the anterior surface of the first cheliceral segment. Males also tend to have long, thin pedipalps relative to those of other harvestmen.
