Camel Spider, Wind Scorpion, Sun Spider, Solifugid
Eremobates spp. (Solifugae Order)
Eremobatidae, Order Solifugae (Arachnid, but not a true spider)
Physical Description
Distinctive large, forward-projecting chelicerae (pincer-like jaws) taking up a large portion of the prosoma. The body consists of two main regions (prosoma and segmented opisthosoma). Highly distinctive long pedipalps held forward like antenna-like legs.
Size Estimate
Body length typically 1 to 3 cm (0.4 to 1.2 inches), total leg span around 4 to 6 cm depending on age.
Coloration & Markings
Pale yellowish-tan to reddish-brown prosoma and appendages, with a slightly darker, segmented greyish-brown abdomen.
Web Type
None. Solifugids do not possess silk glands or spinnerets and do not spin webs.
Eye Arrangement
Two prominent simple eyes located on a small tubercle on the anterior midline of the prosoma.
Leg Characteristics
Four pairs of walking legs plus large leg-like pedipalps equipped with adhesive organs at the tips used for climbing and grasping prey.
Venom & Safety Information
Venom Information
Non-venomous. Solifugids completely lack venom glands and relies entirely on mechanical force from powerful chelicerae to subdue prey.
Medical Significance
Harmless to humans in terms of toxicity. Large individuals can pinch or nip the skin if handled, causing minor localized pain or potential secondary infection if the skin breaks.
Safety Recommendations
No medical danger. If found inside, scoop up carefully using a cup and a piece of cardboard to safely relocate outdoors near garden bed or yard away from doorways.
Habitat & Behavior
Habitat & Range
Widespread throughout arid, semi-arid, and desert regions of North America, particularly the southwestern United States and Mexico. Frequently wanders indoors across floors or near doorways.
Behavior & Temperament
Fast-moving, active nocturnal predator. Extremely fast runner that may appear to chase human shadows to seek shade during hot conditions or bright lights.
Diet & Prey
Voracious feeder on small invertebrates, including crickets, beetles, ants, termites, and other arachnids.
Seasonal Activity
Most active during late spring and summer months when night temperatures are warm.
Description
This unique organism is a solifugid, commonly called a camel spider or wind scorpion. Although an arachnid, it is not a true spider. Recognizable by its massive jaws, segmented body, and leg-like pedipalps, it is a harmless nocturnal hunter that acts as beneficial pest control.
Key Features
Enormous forward-pointing jaws (chelicerae), prominent forward-projecting pedipalps held off the ground, pale yellowish-brown body, segmented abdomen, and lack of venom glands.
Similar Species
True spiders (like wolf spiders) which have unsegmented abdomens and venomous fangs, or scorpions which possess a stinging tail and distinct pedipalp claws.
Life Cycle
Females lay eggs in underground burrows or under debris. Spiderlings/nymphs undergo several molts before reaching maturity, living approximately 1 to 2 years.
Ecological Importance
Valuable desert and semi-arid ecosystem predators that keep populations of agricultural pests, termites, ants, and other insects in check.
Conservation Status
Not evaluated (NE). Generally common across suitable arid habitats.
Interesting Facts
Despite urban legends claiming huge size and extreme speed, camel spiders are non-venomous and modest in size. Their name 'Solifugae' translates to 'those that flee from the sun', referring to their shade-seeking behavior.
Photography Tips
Focus on the distinct chelicerae (jaws) from a top-down or direct frontal angle with good light, taking advantage of moments when it pauses movement.
