Eremobates norrisi is a of solifuge (windscorpion) in the Eremobatidae, described by Muma & Brookhart in 1988. Solifuges are arachnids distinct from spiders and scorpions, characterized by their large, powerful and rapid running ability. Like other members of the Eremobates, this species is adapted to arid and semi-arid environments in North America.

Diet
Voracious of small arthropods, using powerful to capture and kill prey rather than venom.
Behavior
Fast-running, primarily . Solifuges are known for their rapid, erratic running movements and aggressive predatory toward prey. They are not venomous and pose no significant threat to humans despite their formidable appearance.

Misconceptions
Solifuges are frequently mistaken for spiders or scorpions and subject to exaggerated claims about their danger to humans. They are sometimes called 'camel spiders' or 'sun spiders' in vernacular usage, and false rumors about their speed, size, and venomous nature have circulated, particularly among military personnel in desert regions. These arachnids are not venomous, do not chase humans, and do not clip hair from sleeping people for nest lining (the latter claim lacks scientific support).
