Araneus marmoreus, The marbled orb weaver is a colorful orb weaver species. Due to its orange color, it is sometimes also referred to as pumpkin spider. The marbled orb weaver can be found throughout the east of the United States and in Canada.
Marbled orb weaver description
The Marbled Orb Weaver can have several appearances. The coloring can be a bright orange, a mixture of lighter orange and beige, bright yellow with black, pale yellow and black, cream, to brown to even red.
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.
Size
Female marbled orb weavers can reach a size of up to one inch (24 mm).
Web
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.
Bite
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.

Was it that spider?
My grandparents live in Anchorage, AK and have had this spider living in their doorway for a while. I haven’t been able to find a match to it anywhere, but I suspect it might be an orb weaver of some kind.
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: https://www.inaturalist.org/photos/23839199
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.

Hello, my wife picked this up off the ground bc she thought it was a berry. When it moved in her hands she screamed and threw it down. I got a good laugh! I picked it up and put it in a safer area.
Hi, hope you’re doing great. My name is Laura Brambila and was just curious if Marbeled Orb spiders have ever been spotted in CA. Tha k you, just asking for a friend. Hope to here from you soon.
Warm regards,
Laura
P.s my phone will not allow me to download the pic but have one saved for you. Thank you!
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.
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?
Why did you kill him? Spiders are very beneficial for environment.
Hi! Just found one in California! I noticed California isn’t on your list of places they are found.
We saw this pumpkin spider yesterday on our fall walk!

Hi Josh, this is a male marbled orb weaver (Araneus marmoreus): https://usaspiders.com/araneus-marmoreus-marbled-orb-weaver/
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?
