This creature is the second one I’ve seen in the last couple of weeks, both were on the ground, and near a threshold, they dart out then freeze when the door is opened, and are nocturnal. Its about two inches across it antenna (front legs?)

Hi Kim,
Though this creature does move like a Crab, it is not a Crab Spider, nor even a true Spider, but rather a member of its own order.  It is a Tailless Whipscorpion, and it is related to both spiders and scorpions, but unlike the former, they do not possess venom.  They are shy, harmless, nocturnal hunters that will help keep the cockroach populations under control.

Thanks Daniel,
There are small roaches in the yard, so that would explain their presence.  Glad to hear they aren’t venomous, they can hunt in the yard all they want.
Thanks again!
Kim
