We recently moved from Santa Ana, Ca. to Menifee, Ca. nearer my wife’s parents to care for them and one day my wife spotted this amazing spider in her Aunt’s flower garden. She said that the size of the one flower is about the size of a half-dollar. Haven’t seen the spider since then but will keep and eye open for them.

Green Lynx Spider

Dear David,
This is a nice female Green Lynx Spider, one of our favorite species on What’s That Bug? and this is quite late in the year to see one.  Judging by her size, she is eating well, and she may be ready to lay some egg sacs that she will guard.  Green Lynx Spiders do not build webs to snare prey, but rather, they pounce on their prey, often from a great distance.  Green Lynx Spiders are frequently found on blossoms in the garden.

Thanks Daniel,
I will definitely go looking through Patti’s Aunts flower bed come the spring for more of them.  Maybe I can get some on my side of the street here to hunt through my bonsai trees.
Regards, Dave

I found this beautiful spider the summer before last and realized I still had and image of it but was not able to properly identify it. I found it mid August in southern Colorado.

Golden Orbweaver

Dear Christopher,
Your Golden Orbweaver, Argiope aurantia, is of the genus commonly called Writing Spiders because of the stabilimentum woven into the web.

Ed. Note:  We have never heard of a situation where Spiderlings remain together after leaving the female’s protection, and we suspect the “conga line” you witnessed was of creatures other than Spiders.  The behavior you describe is more typical of social insects like ants or immature Hemipterans.  Are you able to provide an image?

There are many unusual bugs in the jungle here, such as spiders and scorpions that carry their babies on their backs.
I was delighted to find your site – thanks!
Can you tell me about spiderlings traveling in a “conga line”, hundreds of them? Why?

Tarantula Spiderling “Conga Line”

Hi again Malcolm,
Thanks for sending an image.  Our initial response to you expressed our doubt that Spiderlings would travel the way you described.  We retract our supposition.  These do indeed look like Spiders.  We will attempt to find additional internet documentation that can explain it.

I believe these are plausibly Brachypelma vagans spiderlings and this article holds a bit of info about what is occurring in this photo.

Ed. Note:  Here is a quote from the linked article:  “The spiderlings, which have a body length of about 2-3 mm, stay in the maternal burrow for several weeks. Little is known of this gregarious stage in this species, although spiderlings have been observed moving around the entrance of the maternal burrow, in where their mother is hunting in a sit-and-wait position. They often climb over each other but avoid contact with the mother. During daytime, the spiderlings were known to remain active and visible at the entrance of the burrow for up to one hour after the female had retreated. They were able to move easily through the web covering laid by the female over the burrow entrance (Shillington & McEwen 2006). Authors hypothesized that the silk network around the burrow provides an important chemotactic cue for orientation (Minch 1978) and juveniles probably remain in contact with this network at all times. After this gregarious period, the spiderlings disperse in the form of columns of about 100 siblings walking away from the mother’s burrow (Reichling 2000, 2003; Shillington & McEwen 2006). Shi- llington & McEwen (2006) observed that during the night of May 24 th 2003, spider- lings left the maternal burrow in three lines. Then at random intervals, one individual left the column and headed in a different direction, causing successive forks in the column. The maximum observed distance of dispersal was 9 m from the maternal burrow. Dispersal is observed in several spider species, including several species of mygalomorphae, all using silk for ballooning (Coyle 1983) or orientation (Jean- son et al. 2004). Previous reports on B. vagans mention that the spiderlings walk in line like ants (Reichling 2000), but no work has recorded the use of silk during dispersal. During their gregarious and dispersal phases the spiderlings do not show any aggressive behavior toward each other, as many spiders do (Gundermann et al. 1986; Jeanson et al. 2004).”

Thank you! That description sounds entirely likely – location, environment, and behavior. And attached is a photo of an adult found outside the house. Who would have guessed? I feel happy to understand the critters here in more depth.
For what it’s worth, I’d wager the spiderlings stay in line visually. From their non-colliding dynamics, and seeing individuals lose their place in line and orient from an inch away to rejoin.
Thanks again.


Hi Malcolm,
Thanks for sending an image of what we believe to be an adult male Tarantula.  We will be featuring your posting for a spell.

This is a picture I took in Mid fall 2016.
It was taken in SW WISCONSIN USA. Vernon County.
It was found on a house (doorjam leading into house) that is built on the bluffs which surround the banks of the MISSIPPI RIVER.
Please help identify.

Fishing Spider

Dear Angela,
Your Spider is a member of the genus
Dolomedes in the Nursery Web Spider family.  Dolomedes species are commonly called Fishing Spiders or Dock Spiders because they are generally found near bodies of water, and though fish do not constitute their primary source of food, Fishing Spiders are capable of walking on the surface of water and then diving below the surface for protection or to capture aquatic prey, including small fish.

I’ve lived in Florida most of my entire life. I’ve never seen anything like this! My fiance is currently in Miami and he snapped these photos. He guessed it was a golden orb weaver of some sorts, but I think not. WHAT in the world is this?

Silver Argiope

Dear Sara,
The Silver Argiope is a relatively common, harmless Orbweaver in its range, including Southern states like Florida, Texas and California, through Central America and into South America.

Hi I was hoping you could identify this spider. There are a lot of them that live out in the field. As you can see in the 2nd photo they often have thick webs in a zig-zag extending from where they put their legs. Thanks.

Silver Argiope

Dear Louis,
This is an Orbweaver, and it really resembles a North American species
Argiope argentata, the Silver Argiope, which BugGuide states is found in:  “CA, TX, FL (mostly in southernmost parts of those states). There’s also one data point from AZ.”  The zigzag web you mention is known as the stabilimentum, and many scientists believe it helps to camouflage the spiders in the web, and the presence of the stabilimentum gives spiders in the genus Argiope the common name Writing Spiders.  According to Colnect, the Silver Argiope was pictured on a stamp from Uruguay in 2009, which is good evidence the range extends well into South America.  According to EcoRegistros, the species is known as the Araña Tigre or Tiger Spider for our English only speakers.  We will be postdating this submission to go live at the end of the month while our staff is away from the office for the holidays.
