My teacher found a spider with a reddish coral colored body (cephalothorax), red and white/clear striped legs, and a black and yellow abdomen that looks like a Rorschach test. The spider was about .5 inch long.

Marbled Orbweaver

Dear spider nerd,
Sometimes we go back a ways through unanswered mail to find an interesting letter to post, and today we happened upon your lovely image of a highly variable Marbled Orbweaver,
Araneus marmoreus.  This is only one possible color combination, but it is a distinctive one.  You can compare your photo to this image posted to BugGuide.

Trapdoor Spider – CA
Location: Berkeley, CA

I saw this spider outside of a well maintained building near a nature reserve in Berkeley, CA. I took the photos 3 nights ago, in mid November; weather has been warm, barely any rain, and with some humidity. It looks to me like a trapdoor spider, but it doesn’t look like ”the” California Trapdoor spider. You’ve gotta tell me, what’s this bug?

Trapdoor Spider

Hi Jim,
You are correct that this is a Trapdoor Spider and you are also correct that it is not the California Trapdoor Spider,
Bothriocyrtum californicum.  We believe it is probably a Tube Trapdoor Spider in the genus Calisoga based on this image posted to BugGuide.

Tarantula

Hi Sean,
Your Tarantula is in the genus
Aphonopelma.  BugGuide has this information posted:  “The Aphonopelma of North American are poorly known. Although many species have been described few specimens can be properly identified either by using available keys or by wading through species descriptions . Most identifiable specimens belong to species found in Mexico or Central America that are easily recognized by unique color patterns, such as that of A. seemanni . Correct identification of specimens collected within the United States is often suspect since determinations must be based on the process of elimination using collection dates and locality data in combination with coloration, coxal setation, and metatarsal scopulation .

Huntsman Spider

Ed. Note: We have already responded to immediately regarding our issues with doing these identifications, but we couldn’t resist posting this image which we believe is one of the Huntsman Spiders in the family Sparassidae, also known as the Giant Crab Spiders

Banded Garden Spider

Hi Jillian,
In our opinion, this appears to be a Banded Garden Spider,
Argiope trifasciata.  You can compare your image to the images on BugGuide.  Orbweavers in the genus Argiope are impressive spiders that attract much attention.  They are not considered to be dangerous, though it is possible they may bite if carelessly handled.

wolf or grass spider?

Hi Bugman,
I’m trying to get a definitive ID on this spider with spiderlings. I took it this summer (2010) at the Nature Center where I work. I’d like to include it in a presentation I’m working on.
It matches some photos I’ve seen of wolf spiders, and I know that wolf spiders carry their spiderlings, but it doesn’t have the really big eyes that I think of as typical for them. Maybe it’s a grass spider? Or something else?
I love your site–I look at it every day!
Thanks for all you do!

Rabid Wolf Spider with Spiderlings

Hi Curious spider fan,
This maternal behavior is consistent with Wolf Spiders and not Grass Spiders which look somewhat similar.  We believe this is a female Rabid Wolf Spider,
Rabidosa rabida, and you can compare your specimen with the images posted to Bugguide.
