Identify a spider with white spots, striped legs, yellow, white design abdomen stomach – Orb-weaver

This spider’s wheel shaped round web made identifying this striped legged spider easier.  Orb-weaver spiders are the most common garden spiders and love to hangout in the middle of their round webs.

This chromatic spider made a web marvel between two large yucca plants.  It was a medium sized spider, a bit scary looking up close; but I was so intrigued with her massive silky web!

The insect that wonders into the female Orb weaver’s viscid web will receive a quick stunning bite.  This spider has over 3,000 species and belongs to the family Araneidae.

Within a few minutes an insect settled on her web and provided a meal for this female Orb weaving spider.  All Orbweavers spin webs.  According to  Female Orb-weavers spin the webs and are seen more often than the male spiders.

It is late summer and spiders are everywhere!  Fall is typically the time the female Orb weaving spiders will lay their last clutch of eggs.   The spider eggs survive the winter and will hatch in the spring.

Another female Orb weaver was nearby on her wheel shaped web.  This spider was gray colored with striped legs and a white design on the abdomen.   The white design on the spider’s abdomen is clear in the photo below.

Orb-weaver spiders only bite if they feel threatened.  Their venom is not harmful to humans.   The bite of Orb weaving spiders feels like a bee sting.  They stay active at night rebuilding and repairing their round shaped webs.

Are Orb-weaver spiders poisonous?    Spiders have venom.  Orb-weaver venom is potent but this spider venom is NOT dangerous to humans.

Orb-weavers and all members of the family Araneidae have eight similar eyes in 2 rows of four.  The spider’s eyes are pretty clear in the photo above.

Orb-weaver spiders can help control your mosquito population and are considered beneficial to have around!

A large, hairy gray spider – Wolf Spider in my Lantana

Wolf spiders are expert hunters and pretty easy to identify due to their large size and hairy bodies.  If touched or threatened a Wolf spider will bite.   I was careful while observing this large gray, grey, Wolf spider that made his home in our Lantana plant.

Wolf Spiders have over 2,000 species and are members of the Lycosidae family. They live mostly solitary lives and hunt alone. Some Wolf spiders will chase their prey and others will wait in their burrow for passing prey.  Wolf spiders are fast runners.

Arizona Wolf spiders are generally hairy with varying colors from browns and grays.  Sometimes this spider will have a pattern along the back of the abdomen and head.  Wolf spiders have good camouflage for living in the desert.  They depend on camouflage for protection.

Gray Wolf Spider Eyes

The photo above and below shows the eyes of the Wolf spider.  They have eight eyes in three horizontal rows;  with 4 small eyes on the bottom, 2 large eyes in the middle and 2 medium eyes on the top.

The light from the flashlight has been reflected from the Wolf spider’s eyes producing a glow in the photo below.  According to the Arizona – Sonora Desert Museum, the eye shine is caused by a tapetum in the eye which reflects light rays back through the eye retina and probably enhances the spider’s night vision. Wolf spiders are primarily nocturnal predators and are rarely seen during the day.

The male Wolf spider has two additional leg-like appendages, called palps, that are attached behind the mouthparts.  These palps are used to hold and position prey and in the mating ritual.  Female Wolf spiders are larger than males.

Female Wolf spiders carry their egg case at the end of the abdomen by attaching it to their spinnerets.  The female spider holds her abdomen up in the air so the egg sac doesn’t drag on the ground.  When the spiderlings hatch they climb onto the female Wolf spider’s abdomen and hold her hairs.

Wolf spiders are capable of defensive bites if provoked.  Symptoms of the Wolf Spider’s venomous bite include swelling, pain, redness and itching.  The skin area at the Wolf spider bite may turn black. Swelling and pain can last up to ten days.

Nevertheless, having wolf spiders is considered favorable because they consume undesirable arachnids.  I’m quite happy to have this Wolf spider guarding our large Lantana shrub.
