Male California Trapdoor Spider

Dear Chainsaw,
This is indeed a male California Trapdoor Spider and it appeared right on schedule, though your September rain was rather unseasonal in Southern California.  It will be interesting to see how changes in our weather patterns will affect populations of native species.  Male California Trapdoor Spiders wander in search of mates after the first rains of the season.

My husband was just given this from a teacher who says it was found wild and they thought it was female. At first we were told Chilean Rose Hair but now thinking California Ebony?? Thanks!

Chilean Rose Hair Tarantula

Dear Stephanie,
Once a wild creature is taken from its habitat and becomes a “pet” and then changes hands, and if a chain of custody cannot be established, it might be difficult to establish actual species identity.  We do not have the necessary skill to identify Tarantulas to the species level, but this does appear to be a female.  Perhaps one of our readers who has more experience with Tarantulas will be able to provide a proper species identity.  As a cautionary lesson to our readers, we would strongly advise folks never to remove Tarantulas from their environment as they are becoming increasing rarer in the wild.  Since they are desirable spiders sold in pet stores, “collectors” frequently remove native species from the wild to sell them, a habit we strongly discourage.

What is this? Maybe the Salt Lake Brown Terantula? Is it a poisonous spider? Saw it coming from a boulder rock wall in Saratoga Springs, Utah.

Tarantula

Dear Daniel,
This is a Tarantula in the genus
Aphonopelma and BugGuide led us to this quote from the Journal of Arachnology:  “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.”  BugGuide does list Utah sightings in August and September.  We searched Salt Lake Brown Tarantula and found a posting in our own archives with the subject Salt Lake City Brown Tarantula, which was not a name, but rather a subject line for the posting, and we also found a Salt Lake County Brown Tarantula identified as Aphonopelma iodius on the Natural History Museum of Utah site where it states:  “The teddy bear of the desert, these harmless fuzzy darlings live much longer than you might think — up to 25 years for a female and about half that for a male!  Tarantulas aren’t the fastest runners.  Their primary defense is the irritating hairs on their abdomens.  When chased or frightened, they can use a back leg to brush these hairs into the eyes or mouth of a predator.   In the late summer, you’re likely to see tarantulas wandering in the foothills.  They aren’t migrating. They are mature males looking for females, with little interest in food or their own safety…just mating.”  We were going to try to link to the species on BugGuide and see if we could get additional information, but alas, BugGuide currently seems to be experiencing technical difficulties.

This spider was found around 10:30pm. It was over 100 F here during the day so I am not sure if the heat confused it? It was found On a driveway near a garden. The legs seem more slender than other pictures of tarantulas I have seen. If you look closely you can notice darker black banding on its legs. Just wondering what it’s species is?

I would be most appreciative if you could identify the spider I found last week walking on my garage floor. I have never seen this particular spider before. Could it be a northeast trapdoor spider? I let him go without harm, I love spiders.
Signature: Thank you!

Trapdoor Spider

Black Purseweb Spider

Though this might be a Trapdoor Spider in the genus Ummidia, based on images posted to BugGuide,  the genus seems to be primarily a southern genus with sightings as far north as Maryland on BugGuide.  We believe a much closer match is a Purseweb Spider in the family Atypidae, like this individual posted to BugGuide.  The Black Purseweb Spider, Sphodros niger, pictured on BugGuide looks like a perfect match to us and you are well within the documented range of the species according to BugGuide.  The spinnerets, the silk producing organs at the tip of the abdomen, are quite distinctive, as are the impressive chelicerae.  You may enjoy the information provided in the Angelfire pdf.

I know it’s a tarantula but just wondering if you could give me an idea on what type! I bought it from a pet store and forgotten what it’s called !!!

Dear Adrian,
With all due respect, accuracy in proper identifications is tremendously aided by knowing the location of the sighting.  Pet stores purchase creatures from all over the world.  Furthermore, the highest quality images are incredibly helpful for proper identifications.  Your dark, blurry, low resolution image is not ideal for a proper identification.  We are not able to assist you at this time.
