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 ...
P. opilio is highly susceptible to some broad spectrum insecticides, so use of such insecticides is discouraged for conservation of P. opilio populations. Some specific products appear to cause less harm to P. opilio , such as Bts .

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. Both sexes have small tubercule-mounted spikes on the anterior surface of their body, in between the top of chelicerae and the anterior end of the dorsum.

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.
