This is an odd looking spider ? Comes out at night, fast ground runner and aggressive when cornered. About a inch and a half long.

Dear C. Ritchie,
Though these creatures are sometimes called Wind Scorpions or Sun Spiders, they are in their own Arachnid order Solifugae, so Solifugid is a more correct common name.  In some parts of their range, they are called Sand Puppies.  Though they are related to both spiders and scorpions, Solifugids do not have venom, so they are harmless, though the bite of a large Solifugid might draw blood.  In the Middle East where they are known as Camel Spiders, they grow much larger than they do in North America, and despite the numerous myths associated with they, they are nonetheless not dangerous creatures.  As your email indicates, they are nocturnal and they are hunters that will quickly dispatch much larger prey.  We receive many photos of dead Solifugids because they appear so frightening.  See BugGuide for additonal information.

  1. we were just finishing our 4th of july bar-b-que, and filling our pool at about 11:30 p.m. , feeling pretty happy that we had all of that finally under our belt, long story, we were sitting there eating some awesome grub, out of the corner of both of our eyes something moving quite quickly came into view, we both almost jumped out of our skin as they say; this thing was three feet long and two feet wide, well not exactly, really only two inches long, but scared the you know what out of us!!! it was a solifugid trying it’s hardest to get under our back door which has an inch gap, that we have been fighting since we moved in !! it’s pretty much blocked but still this guy was trying, i don’t like killing any living thing but, this guy had to go, i mean we’ve had a few in our house already, just babys, compared to this guy so seeing his size and ambition i went into battle ! and this guy did not go easily at all, sparing the details, it took some doing, i have much respect for these earthbound animals!!!

  2. Hello, i thought i’d let you know the genus of this windscorpion.

    she’s (its a female) an Eremorhax species, a large bulky genus found in california, new mexico, arizona, and texas. I do not know the species, however.

    The excessively fuzzy body, enormous chelicerae, and short stubby legs- somewhat similar in appearance to the old world genus- rhagodes makes it easy to id to genus.
