Summary

Hogna is a genus of wolf spiders containing over 200 described species, characterized by their adaptability to various habitats and distinct physical features. They are significant predators in their ecosystems and are found in diverse terrestrial regions across the globe, except Antarctica.

Physical Characteristics

Hogna carolinensis, among the largest spiders in the US, measures 22 mm to 35 mm in body length. The carapace is generally dark brown without distinct patterns. The abdomen shows a slightly darker stripe, with a black ventral side. For other species, characteristics vary including color of sternum, coxae, and venter. Some species, like Hogna coloradensis, have specific dark markings that differentiate them from others.

Identification Tips

Hogna species can be identified by their unique colored features such as a dark area near the epigastric furrow (Hogna coloradensis) or specific color arrangements on the sternum and venters. Species might lack median and submarginal bands on the carapace or have a generally black or dark appearance on various body parts.

Habitat

Hogna species primarily inhabit terrestrial environments, often creating vertical tubes dug into the ground; for example, Hogna carolinensis typically resides in such burrows.

Distribution

Hogna species are found across all continents except Antarctica, with specific regional distributions noted in the continental US and Canada.

Diet

Hogna spiders are carnivorous, primarily feeding on insects and other small arthropods.

Ecosystem Role

As predators, Hogna spiders play a significant role in controlling insect populations within their ecosystems.

Evolution

The genus Hogna is accepted as distinct from Lycosa by contemporary researchers, which has implications on the understanding of their evolution and classification.
