Due to the sometimes bright orange abdomens that it received its nickname as the Pumpkin Spider. Another attributing factor for their nickname is the fact that they are most often seen in the fall time when pumpkins become popular. As the Fall sets in, their abdomens will enlarge, making them much more noticeable.

Usually, mixed within the patterns on its abdomen, are two swirling darker stripes that run side by side down the middle. It is almost wrong to call them stripes because of how much they swirl, and often even touch each other. These patterns give the abdomen a marbled like appearance.


Female marbled orb weavers can reach a size of up to one inch (24 mm).


Like any orb weaver, the marbled orb weaver spins large webs to catch small flying insects. The spider rests in its web and feels the vibrations once a prey hits the web.


As is true for any orb weaver, the bite of the marbled orb weaver is not dangerous for humans. It may cause similar symptoms like a bee sting at worst.

    1. Hi Merritt, you are right, this is a female orb weaver. It took me a little time to figure out which one it is since the color pattern is quite unique. I am fairly certain that this is a marbled orb weaver (Araneus marmoreus). It is usually orange or yellow but sometimes also black and white like the one your grandparents found. Here is a similar looking lady:

  3. I found this spider on my back porch in Wasilla Alaska. I am new to Alaska and have never seen anything like this before. He is extremely fast. Has a web and only came out when a fly got stuck. I found him after he wrapped the fly. I was trying to get pictures but he unhooked his dinner and took it back to his crack in the window seal. One side had a huge black dot and his other side had a different marking. Please help.. Thanks.

  8. My 6 year old son and I were on our way to a ground blind in the woods to do some hunting and not 5 feet from our blind was this spider. I thought it was interesting enough to research this spider so I found out that it is the marbled orb spider.

  9. What kind of spider is this? Is it poisonous? After I killed it an orange liquid came out. Were these eggs? If not why was the body so big and fat?

  10. Greetings and thank you for such a helpful site. Is this a marbled orb weaver? It was on my front door so I relocated it to lovely shrub near garage. 2 hours later it’s back on the front door. Here in Oregon it’s in 40s and pouring rain. The orb spider is currently on my counter in container with leaves, but I don’t know where I can help her relocate to- where hopefully she doesn’t keep trying to become an indoor spider. Suggestions?

  11. Is this an orbweaver spider? If so, what family; if not, what kind of spider is it? It was hanging by a single web-thread on a sliding-door rail outside the basement of my home in northern Virginia on 11 November 2022. Seemed not to be enjoying the fall weather that was spiced by desultory remnants of Hurricane Nicole.

  12. I’m a mail carrier in Brandon, MS. I found this beauty in a mail box while delivering. This is the first time I’ve ever seen one. The colors are so vibrant. I left him chillin in the mailbox.

  13. Hi,
    I’m in RI and this little guy appeared in the rafters of our deck cover. After a little searching I’m inclined to ID as a Marbled Orb Weaver (Araneus marmoreus) but, it’s web is more cob-like than orb and it seems to hang in the middle as opposed the edge. What do you think?
