Spider_Black1Black Widow Spider: The black widow spiders are the most venomous spiders in North America. The females are the most commonly seen and can be identified by being all black with a red hour glass on the bottom of their abdomen. The females are the most poisonous as well and can be potentially fatal. They are called black widows due to their nasty habit of killing their males after mating though upon rare occasions they don’t eat them but only when they have been well fed beforehand. Their webs are almost always built close to the ground and mostly on block walls. They are only active at night and should be avoided. They are a very skittish and shy spider unless there is an egg sac present.

Spider_Black2Wolf Spiders: Wolf Spiders are ambush spiders, they don’t usually build webs and can be found roaming on the sidewalks at night. They aren’t poisonous though and will only bite if handled. They are large brown and gray spiders that are more commonly found through the summer. Females carry their young on their backs and are active hunters.

Camel spiders aka Wind Scorpions or sun spiders: Yes we do have camel spiders here in Utah, this spider goes by several names such as camel spider, wind scorpion, sun spider, and even vinagaroon. This spider is highly aggressive and not meant to be trifled with. It is a larger spider and is luckily not venomous, though the bite is highly painful and some people complain of a vinegar taste in their mouths. They are light colored spiders, mostly tan with some brown on the abdomen.
