Jumping Spider

Abdomen - Gray and white with a splotchy pattern. Somewhat hairy.

Cephalothorax - Approximately the same size as the abdomen, it has nearly the same pattern as the abdomen and two sets of its eyes on its back.

Size - The spider in the above pictures was near the size of a dime if I included the legs.

Bite Info - Not considered dangerous and are listed as No Risk. ....  However, the symptoms of a bite are not always something you want to deal with.  Most cases will have some swelling and itchiness that will fade. Sometimes they can cause aching muscles and on a rare occasion they can cause flu like symptoms with nausea and vomiting that can last a few days.

Other Notes - These spiders are very intelligent and quick to run or jump away from approaching danger. I found this one on the inside of a friends back door and trying to get it on a piece of paper so I can get pictures was near impossible. After some difficulty I finally chased it around to the outside of the door and knocked it off onto his steps where I got the pictures.

Genus - Marpissa muscosa

Running Crab Spider

Notice how flat the Running Crab Spider spreads out to the counter top.

A nice profile shot of this guy

Got him to pose for me to get a shot at his underside.

Abdomen - Round and slightly oblong with an array of design to the pattern and can range from light yellow to a gray in color. Most prominent on the abdomen is usually a white cross.

Cephalothorax - Around half the size of the abdomen, it is sometimes smooth with a hairier head area.

Size - I have seen adults around as large as a quarter, thought that is including its legs.

Bite Info - As ugly as this spider may seem, it is quite tame and harder than most to provoke to bite. When it does bite, it leaves nothing more than some irritation and is completely harmless to humans.

Other Notes - They tend to spin round webs, strung across an open area and will sit in the center (head down) and wait for their prey to fly into its web

Genus - Araneus diadematus

Woodlouse Hunter

Abdomen - Oblong smooth but dull look to it. Usually a cream or tan color.

Cephalothorax - Near the same size as the Abdomen. Has a dark brick red color with large chelicerae (fangs).

Size - The adult bodies usually run around a half an inch with the females usually slightly larger. Including legs the run near an inch in size as adults.

Bite Info - Can cause a blistering rash, but otherwise is not considered dangerous.

Other Notes - This spider has the large fangs for penetrating the armor on beetles, so whether the venom is considered dangerous or not, likely the bite will hurt, so I would not suggest handling them.

Genus - Dysdera crocata
