Who is this spider?
I found at least half a dozen of these spiders tucked under the rims and between the sections of some plant 6-packs in which I’ve got seeds planted. The packs are in flats resting on the ground in the garden. This spider is about an inch long; some of the others looked smaller. The web is very white. I’m in Glendale (Los Angeles) California. From general body shape and hairiness I suspect a jumping spider, but couldn’t find any pictures of one with this lovely orange color. (Your fall 2005 web page was down when I went looking for a picture.)

Hi Sallie,
This is one of the Red Jumping Spiders in the genus Phidippus, probably Phidippus formosus. These are hunting spiders who do not build webs to trap prey, but adult females, according to Hogue, “construct a funnel-like web that is usually in contact with the soil; this structure is used as a retreat for the adults and a safe repository for the eggs.”

two unidentified spiders
Dear Bugman!
I have here two photos of different spiders. The male with the orange abdomen has eluded ID for too long! I happened to catch him while loving on his woman. He presented her with a grasshopper, and while she munched happily on her tasty treat, he got around to more importnat things. I managed to take a nice succession of photos, but this one had the best representations of both of them. I don’t need to tell you how awesome it was to witness this event. The second photo is a small spider with moderately long front legs, the first two pair I believe, found on the wall. He folded his legs up tight in response to my camera in his face, so I couldn’t get him to pose. I took these pictures West Texas this month.

How romantic is that Wendy?
We love your courting Jumping Spider photos and the story as well. Your Jumping spiders are from the Family Salticidae, probably the genus Phidippus, and possibly Phidippus formosus. Hogue writes: “The brilliant red abdomen of this species frequently attracts attention in the spring, when it is most active. … The Red Jumping Spider is not considered dangerous, although its bite may be painful to sensitive persons. Like all jumping spiders, it has a pair of very large eyes. This is a hunting spider and thus does not use a permanent web for trapping prey. … Both sexes spend the daylight hours wandering over the ground and vegetation in search of small invertebrates, upon which they may leap from some distance.” Your spider might also be Phidippus insolens, which exhibits dimorphism in both sexes, meaning that the males and females are differently colored as well as having different color variations within the sex. One form has a black cephalothorax and red abdomen like your photo. Your second photo might be a Domestic Spider, Theridion tepidariorum.

Hairy Black Spider With Fluorescent Green Fangs!
Hellloooooo, Bugman!
This tiny but scary looking black spider with green fangs lunged at me while I was taking it’s picture. It isn’t that big, I’d say about the size of a dime. I found it under a foam swimming pool raft that was hanging over my fence. I live in Northern NJ and I haven’t seen many spiders like this in the area. I’m guessing it’s a jumping spider based on it’s size and the fact that it JUMPED at me!!! Our first child is on his/her way; do I need to worry about this spider being poisonous?
Cool site, keep it up!
p.s., I have high-res (3MP) photos if you want them!

Hi Pete,
Thanks for the beautiful photos of a Jumping Spider from the family Salticidae. This is a large family. The spiders are generally small, hairy and often iridescent or brightly colored. They do not build webs, but leap at their prey. Your action photo is awesome. Perhaps your spider thought you were a fly. There are reports of bites, but they are mild. With infants, though, the bite could be more serious. Spiders are not inclined to bite though unless provoked. Thank you for the offer of higher resolution photos, but we generally post very low resolution images to keep the download time on the site more manageable. Also, thank you for the compliments.
