Parson Spider

Parson Spider

Dear Spider man,
This distinctive spider is a Parson Spider in the genus 
Herpyllus, probably Herpyllus ecclesiasticus.  Like most spiders, it has venom, and like most spiders, it is not considered dangerous to humans.  It is unlikely that it will bite a person, and if a bite does occur, there will likely be nothing more than local irritation.

Hello again, this is Cicada lover. I am wondering if you could identify these other insects and arachnids I have failed to ID. Number one is a spider I found which appears to have a red Christmas tree with a star on top. (I could be wrong) but I didn’t think this was a black widow because their legs are longer, and I have found no black widow spiders with a “star” on top of the red blotching. The spider was found in Waterset (a neighborhood in Apollo Beach FL). The next bug is a caterpillar which was found in a nature preserve called Circle B Bar Reserve in Fl. Picture number 3 is of a…… is of a thing that’s like a beetle with no hard exoskeleton. it was also found in Circle B Bar Reserve.
P.S., Thank you for ID-ing that Cuckoo wasp!
Also, the quality is not that great because I had to crop the photos in order for me to send this.

Dear Cicada Lover,
We are more than happy to continue to identify your mystery insects, however, please confine your submissions to a single species unless there is a very good reason to include different families or classes of creatures in the same inquiry.  We try to keep our archives correctly classified and it is very confusing and additional work to split one submission into multiple postings.  Your spider is a Ground Spider in the family Corinnidae, most likely
Castianeira crocata, and it has no common name.  Its markings are quite distinctive and this image posted to BugGuide matches nicely.  If you resubmit your other images each on its own form, we will attempt additional identifications.

This spider jumped the sliding glass door ledge, and bolted into the house toward my kitchen. I had never seen anything like it here in the Dallas city before. It’s flashy red coloring made me wonder if it were poisonous, and well…I squeeshed it. The pic was taken today. However, he was squeeshed on Saturday, July 25th.
Signature: not sure what you question is here.

Unknown spider

Ant Mimic Spider

We have tried unsuccessfully to identify your Spider, and what we find most troubling is that we believe we have a photo of this species posted somewhere in the over 20,000 postings on our site.  Perhaps one of our readers will be able to assist in this identification.

Update:  July 30, 2015
Several folks provided comments indicating that this looks like an Ant Mimic Spider,
Castianeira amoena, and we are in agreement, though when the image first arrived, it looked like a hairier spider than an Ant Mimic.

Hi Danielle,
Your spider is a harmless Ground Spider,
Sergiolus capulatus. You may verify its identity on Bugguide.  We haven’t posted a recent image of a Ground Spider since 2006.

Hi there. I’ve been getting a few of these spiders coming inside for a visit. This most recent one had a bit of yellow to his marking. They all have the pincers that extend from the abdomen. Am guessing they’re wolf spiders, but not sure.
This particular spider was tangled in a mouse glue pad and was easy freed outside once I got his leg free. Thanks for helping identify.

Western Parson Spider

Western Parson Spider

Hi Kevin,
This is a Parson Spider in the genus
Herpyllus, and thanks to your letter, we now know that there is both an Eastern Parson Spider and a Western Parson Spider, Herpyllus propinquus.  According to BugGuide:  “H. propinquus is basically identical in appearance to H. ecclesiasticus, and examination of reproductive organs is needed for positive identification.”  What you are referring to as “pincers” are actually spinnerets.  Because of your kindness releasing this hapless Western Parson Spider, we are tagging you as a Bug Humanitarian.
