Jumping spiders

[Cockroach]

Last night I caught a small jumping spider, and I put it in a jar to observe it and let it go. After a while I decided to place a tiny Lobster Cockroach in the jar with it to see what would happen, and when the roach crawled near the spider....WHAM! It pounced on the roach and killed it!
I've decided to keep the little guy or gal, so I have some questions:

- how often to feed a spider that's only around 1/8" long?

- how I'd set-up an enclosure for a small jumping spider?

- what's the average life for a jumping spider?

- are they aggressive towards people?

- is their venom able to harm someone if they get bit?


Thanks for any responses ahead of time.

i have kept quite a few jumping spiders over the years. as far as i now they are not poisonous. they are quite fast so holding them really is not possible. they are more curious than aggressive. they will stare at you trying to figure out what you are. i catch all of mine on buildings so i keep them in a small kritter keeper with no substrate mist once a week. they build their webs in one corner on the lid. i drop in a pinhead about once a week. maybe two only if it finishes the first. they also like small moths from outside. i dont know how long they live. the longest i have kept one was 4 months. they are definetly cool to watch hunt. keep the enclosure near a window. they crave sunlight and do not do well in the dark.

Thanks very much. I don't have her anymore. I opened the top to the container, and she got out. I'm gonna try to catch another one soon. Thanks.

Jumpers

The jumping spider, Salticidae, are argueably the most diverse group of spiders in the world. They come in a fantastic array of shapes, sizes and coloration.
One thing that nearly always makes a jumper easy to identify is the two giant 'headlight' eyes. These eyes and their associated neurology take up about 2/3rds of the spiders brain cavity.
In reply to one question, there is only one spider in world that does not have venom, an extremely unusual orb weaver.
Figure that all spiders have venom. As far as them applying that to homoerectus, it is a question of the spiders intent and ability.
One should also keep in mind that virtually every person in the world is bitten many times each day by some member of the Arachnida family.

As a general rule, it is almost impossible to get a salticidae to bite you. There have been reported bites where the salticidae has become trapped, squashed, and brought it's fangs into things.
However, the salticidae is, for a spider, apparently highly evolved. It qualifies what is to be bitten by what is suitable prey that it can jump on and subdue. Since it doesn't bite just anything it jumps on, it is capable of discerning what is eatable, biteable, and what isn't. In turn this indicates the spider has some form of reasoning ability. The ability to discern what registers in it's eyesight as can be eaten. Added to this is the fact the Salti will eat dead creatures as in people killing flies for their pet Salti to eat. Now we have defined a very specialized hunting (and biting) ability.
To make a long story short, unless you manage to look like a suitably edible creature, the jumping spider simply doesn't consider a human something that should be bitten.

Salt's will bite when Trapped, IE pinch holds and forced agenst the skin and are in grave fear for their survivol and unless your watching them you probably wouldn't even notice. Thought I'd just add that one The shark

I wanted to ask a quick Q. There are ALOT of tiny jumping spiders on my cacti. I love these lil guys. They will jump on my hand and run around and jump off. They stare at me...Well they are the cutest things. But anyway, I considered capturing one or two. How can you tell the males and females? i didnt want to get a male.

I was watching a show a while back on jumping spiders that was talking about there intelligence. They said they are the most intelligent iverts and have the ability to talk to one another. They compared them to a three year old child.

Cephalopoda are more inteligent ivertebrates... if we know what the 'inteligence' is and how to measure it
Yes. jumpers are really talkative, especially 'fighting' males.
