Platycryptus undatus


Came home today and looked to the small table by the apartment door and saw this little cutie.

This is a Tan Jumping Spider, Platycryptus undatus, probably a female since its body length was 13mm.

I scooted her into a jar and spent about 40 minutes taking pictures of her before releasing her into our balcony garden. As with most jumping spiders, she was quite curious about what was going on and was always very interested in visual changes (jumping spiders hunt visually and don’t build webs for themselves, although some will steal food from other spiders’ webs).

I named her Georgette. :)



 Jumping Spider - Platycryptus undatus - Female

Found this lovely little girl today climbing the curtain behind my bed. :) A wonderful surprise for such a nasty cold day!
She looks very thin, I have been raising some fruit flies to feed my other tiny spiders and my Black Widow so she will be a happy camper inside till it warms up some.


Found a little tan jumping spider in my bathroom little while ago.. She was so precious gosh.. So when she was jumping away and was about to go to the blinds but she stopped and turned around to face me one last time then she waved her pedipalps around bunch and then they sort of vibrated then she vigorously waved them one last time and then she turned around jumped onto the blinds and that where she is now. I think she was spider yelling at me.. Like yo… I think this little spider just flipped me off. That is so dang cool.


Do Not Kill

Found this pretty gal today at my mom’s house!

She’s a little Platycryptus undatus or tan jumping spider. They move in short, quick bursts so they can be startling to find but do not squish! They are harmless to you and not aggressive. This one was quite gentle (and fuzzy, lookit all that fuzz!), and she was amicable to being relocated to the garden bed after a few pictures.

280 days of Urbpandemonium #38

I opened a door to an office–it was a small building and the office opened directly to the outdoors, where I was. I poked my head in and interrupted a conversation between 2 of my coworkers to tell them about my observations regarding carpenter bees and paper wasps around their building. As I was exlaining that these scary insects weren’t really anything to worry about I became distracted by this beautiful little jumping spider Platycryptus undatus. It was on the open door and jumped to the sidewalk. I dropped to the ground on my hands and knees to photograph it, cementing my reputation at work as the weird bug guy.


Here’s today’s spiderbro. He’s a Platycryptus undatus, or tan jumping spider. They can jump pretty far and throw up their front legs to intimidate others. They’re pretty bad ass and won’t hurt people. Insects are another thing entirely however. There’s an annoying fly that got in the other day that I hope he kills soon. His body is about 5/8 of an inch. With is legs he’s about ¾ of an inch.
