None of the jumping spiders are considered dangerous. I've handled and photographed hundreds of them without incident. Don Cadle, who is also very experienced with jumpers, described getting bitten by the largest known species in this forum message.

I don't know of any spiders in the U.S. that are unusually aggressive towards humans, but there are plenty whose behaviors are commonly misinterpreted that way.

Jumping spiders have, by far, better vision than any other spider family, provided by their two large forward-facing eyes. When any of their other eyes detect movement, they quickly turn to face this movement. If that movement is you, and you aren't an insect, then you have nothing to worry about, even if the spider starts walking towards you. :-)

Shy, marvelous and beautiful... I have to agree with Carol.

I'm no expert but I can attest to the fact that these spiders are not agressive or poisonous but any spider that feels threatened will defend itself, and can bite. Jumping spiders are notorious for raring up, especially in front of cameras, when they can see their reflection, or if you move quickly in front of them (after all, you could be food or a predator). Phidippus jumping spiders are shy, marvelous and beautiful! Enjoy them.

I appreciate your help.
