Olios is the largest genus of huntsman spiders, containing 165 species. They are found throughout the world, with most species occurring in hot countries. The genus was first described by Charles Athanase Walckenaer in 1837.
Description
They are small to large Sparassidae, that have eight eyes in two partially straight rows. For the smaller species of this genus, they are usually light brown to brown with darker areas. Most larger species are darker, and some members of this genus may also be green. They are nocturnal hunters.
Venom
Like most spiders, members of the genus Olios are not considered dangerous to humans. While they do possess venom, it is primarily used to subdue its prey, which consists of insects. The venom is not potent enough to cause significant harm to humans, and bites may result in mild symptoms such as redness, swelling, or pain, similar to a bee sting.
Habitat
As this genus is widespread, they are found in a large variety of habitats, from savannahs to rainforest. They are mainly found in vegetation, and rarely houses. They are sometimes shipped alongside fruit, but this is not a common occurrence.
Species
, this genus includes 165 species and five subspecies.
