Cat Face Spiders Are Invading Colorado!!

Cat spider - Jewel spider in Colorado

Cat Spiders, as most people like to call them, have been popping up more and more around Colorado within the past few years and that’s just based on the number of Facebook posts of people saying “OMG, What is this!? Look how big it is!“. Araneus gemmoides, commonly known as the jewel spider and cat-faced spider, is a common outdoor orb-weaver spider found in the USA. These things are huge, unlike what most of us are used to seeing in our homes and even around our yards (at least in the city).

They make beautiful circular webs, like the kind we’re used to seeing on National Geographic Channel and what makes them so creepy, in addition to their size, is that they don’t bother trying to hide when you get near them. It’s as if they know we think they can kill us, but their venom is harmless to humans so don’t fret.

Also, the mothers, which are the huge ones, die soon after they give birth to a couple hundred micro spiders that can literally fly on a strand of silk in the wind. But that’s only after they try to eat one another first. So, yeah, you have every right to be creeped out.

 

Have you ever seen this type of spider before?

If you have one in your yard take a picture and post it on our facebook page. Facebook.com/ImFromColorado

September 15th, I had one that spun it’s web onto the chain links of our outdoor dog run. I thought is was BEAUTIFUL! I tried to take a picture but couldn’t’ get her in focus. Next day she had moved to the other side of the kennel, didn’t see her again after that, but we now have 3 or 4 tiny replicas of her spinning webs on the kennel. I read that they change colors (need more info on why) she was a rusty orange color.

Mine has let me get as close to her as 2 inches with my camera. She’s not afraid of me and I’m not afraid of her. She has kept a huge potted heirloom tomato plant of mine, free of bugs and yes her webs are beautiful. I,also, have never seen one before this year. I don’t know where she will go for the winter, but I’ll put up the “No Vacancy ” sign on my door! She is very scary looking up close….I just call her Pretty Girl….I live in Pinewood Springs

Well, the first year we had them, Ariadne … was spinning, and I didn’t know… over the door… I open the door, she swings into.. my HAIR! I was like, Aieeee! and she was like ARGGHH! ARGHH! and as she swung back out (picture a bungie cord) she ran all the way up to the roof hollering, “Monsters!” Well I am a lot bigger, afterall. When I realized she didn’t want to be anywhere near me either, we both calmed down and I watched her beautiful weaving. I took a video of it. It’s so painstaking. It takes over a… Read more »

Found 2 in my parents back yard yesterday. The smaller one either got eaten by a bird this morning or packed up and left.

I wonder why I’ve NEVER seen them before until today…

I’m sending a picture. This one is on the front porch. It had a fly on Monday, a bee on Tuesday and a miller moth on Wednesday. They don’t come in the house. If their web is messed with they roll it up and move.

i had one of these years ago in my home and freaked out. I took it to the outdoor extension office and it was labeled as a common garden spider which indeed is an orb weaver. We witnessed some incredible webs! Absolutely harmless but they are very creepy looking.
