Description

• Euagrus is a genus of mygalomorph spiders in the family Euagridae. These spiders have sturdy bodies, strong legs and prominent downward-pointing fangs. They are generally brown to dark in colour and are adapted to living in concealed retreats rather than catching prey in aerial webs. Many construct silk-lined burrows or retreats in soil, rock crevices and other sheltered spaces. They are typically secretive and spend much of their time hidden.

Range

• Euagrus occurs primarily in North America, including Mexico and the southwestern United States, with species occupying a range of dry and subtropical environments. The genus is present in Zihuatanejo, Guerrero, Mexico.

Habitat

• Members of this genus inhabit terrestrial environments, including rocky slopes, dry forest, scrubland and areas with suitable crevices or burrowing substrate. They may live beneath stones, in rock fissures or in silk-lined retreats in soil. They generally remain concealed during the day and emerge to hunt when conditions are favourable.

Diet

• Euagrus species are carnivorous predators that feed on insects and other small arthropods. They typically ambush prey near the entrance to their retreats, using their strong legs and fangs to capture and subdue it. They do not rely on a large prey-catching web.
