Order Solifugae - Windscorpions

Classification
Kingdom Animalia (Animals)
Phylum Arthropoda (Arthropods)
Class Arachnida (Arachnids)
Order Solifugae (Windscorpions)
Other Common Names
Solifugids.
Camel Spider, Wind Scorpion, Sun Spider (these names are all somewhat deceptive as the creatures are not closely related to either scorpions or spiders, though they are in the same class, Arachnids).
Pronunciation
Solifugae (SOLE-ee-FEW-jee), solifuge (SOLE-ee-fuge), solpugid (sol-PEW-jid), Eremobatidae (air-ee-mo-BAIT-ih-dee), Eremobates (air-ee-mo-BAY-teez), Eremorhax (air-EE-mo-rax) Galeodes (gal-ee-OH-deez), Ammotrechidae ("ammo" as in ammunition: ammo-TREK-ih-dee).
Explanation of Names
Etymology:
sol, =a (L). The sun
fug, -i (L). Flee, dispel

"Sun-fleers" These creatures are nocturnal and if found outside in daylight will seek the nearest shade.
Numbers
Worldwide, more than 1000 species in 140 genera.
Size
Most species in the USA reach about 25 mm in body length (about an inch).
Identification

Eight-legged, somewhat scorpionlike, but lacking the tail. Elongated pedipalps look like an extra set of legs, but are used as sensory organs, similar to antennae.


The identification of solpugids to species is extremely difficult. Researchers typically identify them to species-group level, such as Eremobates sp. palpisetulosus group. A large-scale, world-wide revision is currently underway. If you find specimens and would like to contribute to the research, please visit this site for information:
Range
Habitat
Warm and arid places. Mainly deserts and sandy places, but some species are found in forests and grasslands.
Food
Voracious predators: Invertebrates and small vertebrates. Will scavenge on dead creatures as well as hunt live prey.
Remarks
Although they lack venom, the strong jaws of these creatures may inflict a sharp bite in self-defense if handled. The most common species are quite small and can hardly be felt except for a slight "pinch". Larger species, such as in the genus Eremorhax, have been known to draw blood, which should be immediately disinfected as one would treat any bite.
According to Wikipedia: "Solifugae are the subject of many urban legends and exaggerations about their size, speed, behavior, appetite, and lethality. They are not especially large, the biggest having a leg span of perhaps 12 centimeters (5 in)."
Biodiversity Explorer says: "They vary in size and in the arid areas of southern Africa they can reach 70 mm and with legs included, can measure 160 mm."
