Like delicate lace, so the threads intertwine, oh, gossamer web of wond’rous design! Such beauty and grace wild nature produces…
Yes, ’tis that special holiday, ’tis Halloween. And we manage to gravitate toward all manner of spooky things and transfer our fears anew to many elements of the natural world such as bats, wolves, and spiders. One of my favorite arachnids is aptly particularly evident this time of year – the Marbled Orbweaver, Araneus marmoreus. It’s relatively large size and bright yellow-orange colors make it particularly noticeable in October and gives rise to a couple of its other common names – Pumpkin Spider and Halloween Spider.
Last week I was changing cards in my trail cameras in our woods and took my camera along in case I saw anything interesting. I’m always checking for spider webs in my path this time of year as many orbweavers reach their peak size and, therefore, apparent abundance, in October. I try to avoid the silk-in-my-face greeting of most of these weavers by doing the forest side step if I spot the web or one of the often long anchor lines. This species creates a hide outside the main web, a fact that I appreciate as it means you are much less likely to have a crawling spider on your head or face if you should miss seeing their gossamer handiwork in your path. When a prey item lands in the web, she can feel the vibrations and rushes out of the hide to subdue her meal. I suppose if you are such a noticeable bright color, it pays to have a place to conceal yourelf from would-be predators.
I soon spotted a beauty highlighted in the the dappled sunlight in her holly leaf shelter on our south slope. I stopped to admire her intricate black patterns on a bold yellow background and grabbed a few photos.

Walking a few feet more and I missed seeing another silken line and got entangled in a large web of another Halloween Spider. When I pulled on it to free myself, the owner dropped out of her hide onto the ground and scuttled away (a common defense strategy), but not before I managed a photo as she crossed an equally colorful fallen leaf.
This Halloween Spider dropped from her web and scurried under some leaves on the ground, allowing me only a photo before she disappeared.
As it turns out, this beautiful species is the subject of an article I wrote for the October issue of Walter magazine. Last year I was approached by the magazine editor (at the suggestion of some of my former co-workers at the NC Museum of Natural Sciences) and asked if I would be willing to write a monthly nature column. I had heard of this publication, but wasn’t that familiar with its content. After looking at it, it struck me as a quality magazine that I likened to being similar to an Our State magazine for the Triangle area. They have high production values and I am impressed by the quality and range of topics covered. I encourage you to take a look and subscribe if you agree. Here is a link to this month’s spider article with more information and photos. You can search for my other monthly articles (starting last January) in the archives by putting Nature in the search box on their website and scrolling through the articles. I must admit, I never thought I would have my photos of spiders and the like next to advertisements for Rolex watches, but, it’s a good chance to reach a broader audience.
And here’s wishing you all a safe, sweets-filled, and Happy Halloween!
Fantastic images of this!
I saw my first Marbled Orbweaver this fall right behind my home. Their color is so striking! I enjoyed your post!
Thanks, Mary Kay. I have seen several in the last week, always a delight.
