The hacklemesh weaver (Callobius bennetti) is a spider that is typically found in northern Europe, and in recent years, in regions of eastern United States. This species of spiders is characterized by the lighter colored unique pattern that can be spotted on top of their oval-shaped bodies. Like most spiders, they have eight legs and eight eyes. Another way of identifying this species of spiders is through the untidy web that they weave. The web is typically messy-looking and has a tunnel-like feature which is designed to capture and eat prey at high speed.

Their legs reach a length of about 12 in (30.4 cm) and males of this species also have a pair of rather intimidating fangs. A female hacklemesh weaver grows to have a larger body than its male counterpart and also is more aggressive than the latter. These spiders are typically found in damp areas such as basements of houses, crevices in rocks, and between the barks of trees during summer or spring seasons.
