Neoscona crucifera – Spotted Orb Weaver

Neoscona crucifera, commonly known as the spotted orbweaver, is an orb weaver species indigenous to the Eastern part of North America.

Description of the spotted orb weaver

The abdomen, which is usually a shade of brown or reddish brown, has a slight pattern but nothing that stands out, and is usually covered with thick hairs. The legs will have brown or red-brown coloring closer to the body and have black and white / tan bands on the half furthest away from the cephalothorax.

In Texas, Colorado, Arizona and New Mexico, the range of the spotted orb weaver overlaps with the western spotted orb weaver (Neoscona oaxacensis). Most of the time, these two species can be distinguished. However, since the western spotted orb weaver can take on various appearances, it might look similar to Neoscona crucifera. Both of these spiders are not medically significant.

Size

The body of the female adult will grow to ¾ of an inch (19 mm). If you include the legs, they can reach around 1 ½ inches (38 mm).

Web

As any orb weaver, the spotted orb weaver spins webs to catch small insects. The web is orb-shaped and is rebuild every day.

Bite

The spotted orb weaver is not an aggressive spider. However, in some situations, it occurs that it bites a human or a pet. The symptoms are usually comparable with a bee sting and will not have any long term negative effects.

  1. Hello John, thank you for getting in touch! This is a spotted orb weaver. It is not a medical concern for humans and great to have around for insect control. I’ve moved the comment to our info page about the spotted orb weaver.
    Let us know if you have any other questions.

  2. Found a Hentz’s (the pale tan/khaki ones) tonight (1/2 hr ago), of all the places, in my dining room, weaving a web from the patio curtains to the pull chain fob on the ceiling fan, a good 3 feet reach.

    We live in the country, and I would wager that while I was working this afternoon, someone (likely the 10 yr old) left the patio screen door open a crack, and she walked in.web had to be 90% done when I found it, was kind of a shame to have to knock it down while I caught her up on a house broom, then managed to deposit her outside on the patio where she belongs.
    Didn’t think to get a picture until too late, oh well.

    I was actually headed over to close the patio glass before going to bed, which is why I found it.

    We kill Recluses in the house mercilessly, but we don’t see too many IMO because we deliberately try not to kill off wolves and jumpers that find their way indoors (and especially into the basement).

    1. Hello Aaron,
      Thanks for not killing the orb weaver and setting it free outside. It will be able to find a new place to set up its web and catch some insects. They are quick at setting up a web.

    1. Hello Paula, thanks for reaching out. This is definitely a harmless orb weaver. Since the abdomen is a little dark in the picture, I can’t say for sure what species. I would say a Neoscona sp. orb weaver. Possibly spotted orb weaver (http://usaspiders.com/neoscona-crucifera-spotted-orb-weaver/). The two visible white markings look a bit like Neoscona oaxacaensis but since you found the spider in Virginia that would be out of their natural range and rather unlikely.

  3. This is Spidey Widey. It has been around since it was a baby. Has made beautiful webs!! Has disappeared a couple of times due to cooler weather but has reappeared when it warms up. He/She is not building the web it once was..just want to confirm that it is a spotted orb weaver and ask if its possibly pregnant??

  4. This is a dark picture, but this girl was outside on some foamular insulation in our yard. She has a brown, shiny, translucent thorax with a matte (haired?) darker abdomen with a very faint, lighter chevron pattern. Long legs that alternate from brown to black in segments. I thought the mouth parts were interesting…there seem to be two sets?
