Is it ok to release a non-native spider into the local ecosystem?

Is it ok to release a non-native spider into the ecosystem? Specifically, a red backed jumping spider (Phidippus johnsoni), which is native to the U.S. west coast into suburban Massachusetts. The spider made its journey as a stowaway in a bag of grapes. I should also mention that it is a female, so conceivably could be carrying fertilized eggs.
EEEEEEEEEEEEEEEEEEEEeeeeeeeeeeeeeeeeeeeee! NO! Eww!
Flush it!
(I'm pretty sure my wildlife-biology-Masters-student sister would agree with the rational part of my suggestion.)

No. As much as I applaud your concern for nature, you should be more concerned about the potential consequences of invasive species. Squish the little bugger and be done with it.

I love those little red backs, but no, don't release it. the invasive species problems are not worth the life of one bug.

I think there was something in one of the Star Trek movies about this - it's better for one to die than to risk the lives of many.

Instead of killing it or releasing it maybe you should keep it in a terrarium and see what happens.

You can't possibly be the only method of transport across the continent. I wouldn't worry about it one way or the other. No doubt some have made it to MA and there's no apparent invasive behavior. But if I found a bug in my house I'd squish it in a napkin and be done with it. You can bet I'd not ask a bunch of strangers what they thought about it.

I never kill anything unless it's biting me. The cockroach I flushed haunted my dreams (not a pretty thing).

I agree with kc0dxh, this can't be the first time this particular kind of spider has made this particular journey...
Moreso, if this were the first time... I personally would go forward with the experiment. Sure something disastrous and horrible and catastrophic might happen; but on the flip-side... maybe it wouldn't?

Aw, don't kill it. It's not going to take over an ecosystem all by itself. If you had a suitcase full of them, that might be a different story...

Response by poster: Maybe I should have posed it another way, does anyone have any information on the dangers of releasing non-native species into a local ecosystem where there exists a strong unregulated (or virtually unregulated) transportational infrastructure between those two points that has existed for many years (e.g. in this case, over a century)? Particularly something that touches upon the differing types of climates and/or species (or similar species and climates) of the ones in question, etc.

Release it. As others have said, it can't be the first to make the journey and since you took the time to identify the spider, determine it's origin, and post this question, you are clearly not someone who wants to take the critters life.
If you are really worried about the impact of releasing it, follow dgeiser13's suggestion and set up a little terrarium.

Follow up: I think the problem you may encounter when looking for this kind of information is that if there is a strong unregulated (or virtually unregulated) transportational infrastructure, it's going to be difficult to empirically track the effect of an invasive species. There is no control to see how many were introduced and at what time.
The best I could suggest would be to look at the introduction of the cane toad in Australia. I'm sure it wasn't introduced to the entire continent, it had a staging point and spread out from there.
The problem with this example is that it more strongly filled an ecological niche than several native species, I don't think your spider would have the same impact.

Scientists tell us spiders play a vital role in the ecosystem. They kill pests, keep nasty bugs like mosquitos in check and spin beautiful webs that keep pigs from being slaughtered.
That being said: Science is wrong. Spiders are bloodthirsty killers. If you release her, she will come back late one night and take your firstborn from you. Then she'll come back for your pets. Then, she'll come for you. Rest assured, if a spider accidentally brought Java_man from California to Mass. in a bag of grapes, she wouldn't think twice before squashing you.

I think you should let it go in the garden. If it was a different land mass, I'd say kill it. But it's the same country, a very motivated spider could have walked of its own accord.
(Ok, maybe not, but over several generations a family could have made the journey. Like a giant slower than light spaceship travelling between stars, only with no people, and no stars).

I'm going to argue against killing it.
If you're going to kill it, though, don't salve your conscience by appointing yourself representative of the ecosystem. You don't know the effects of releasing this spider. No one does.
If you're going to be the sort of planetary inhabitant who just randomly kills everything and anything that comes into your path, fine - it's quite trendy these days - but don't try to soft-soap it.

Best answer: The question is bigger than just the one spider. The addition of your new pal and successful hitchhiker could do one of several things that might be less than desireable. Your spider could tip the balance between a low-level just hanging in there population of other red-backed jumping spiders to one that has enought spiders to cause a massive population boom (i.e. create a critical mass needed for exponentail growth and a nuisance population of nonnative species). Or your spider might be carrying a parasite or pathogen that is especially lethal to your native MA arachnids. Then again it might not cause any problems. But why risk it? The US already spends billions each year to combat invasive species and that is just a drop in the bucket compared to the economic and environmental costs we shoulder because of invaders.
In general, it is never a good idea to release a non-native species into a new system. We don't have to go as far as New Zealand to see this. In the western US we are plagued by all sorts of species from the eastern US that were intentionally introduced or just hitchhiked over. Examples include: American bullfrong (Rana catesbeiana), rusty crayfish (Orconectes rusticus), American shad (Alosa sapidisima) and smooth cordgrass (Spartina alterniflora).

You seem not to want to kill the spider. A terrarium would quarantine her effectively. It's not just the spider herself, but any mites she could be carrying, or diseases that she's immune to and local six-to-eight leggers are not.

This isn't a strange species, this is an alien species. We've seem the damage that this can do, heard many examples in the thread, and are advocating the best course of action.
OTOH, submitter can plant some kudzu in their backyard to keep it company, if they're not concerned about this sort of thing.

In good conscience, you can't release it because you don't know where it's been (it could have something the locals can't handle), and you don't want to read in the paper 30 years from now they took over several states.
Just keep it in a terrarium and take good care of it. You can buy crickets in the winter to feed it, and they're probably cleaner than wild-caught crickets anyway, since you care about the quality of her life. How long can it live, a year? This is not a lifetime comittment, if you want to keep it, keep it. (But please, stuff cotton balls in the air holes, as you do not want to get up some morning and discover her progeny are small enough to escape.)
I think this is one of those times when "giving it back to God to take care of" is just not the right thing. That only works if it came from around here and has a lot of friends to play with. Yes, I have spent far too much time explaining nature to children, why do you ask?

If I ever found a strange species of mouse or bird in a bag of grapes or other store-bought food item, I would call animal control and have THEM decide the fate of the beast. I would make this call from outside my house, as I would probably have run out of it mindlessly screaming. My guess is animal control would kill first and autopsy later.
I would also alert the grocery store, and investigate the possibility of a refund. It's probably not worth it for a spider, but it damn well would be for a bird or mouse. What the hell kind of question is that? Has anyone ever brought home a bird or mouse from the grocery store by accident?

I did some research yesterday to try to discover if this little guy had gotten out before. Interesting that while folks had mentioned the pains of alien species in New Zealand, nobody mentioned that this very spider came across to NZ via grapes. Apparently this "spiders on grapes on a plane" thing became a big enough deal for NZ to shut that shit down in 2001. This page seems to indicate that the California Grape Spider Export market is booming and the result of our hippie agricultural methods, but I have a hard time believing the veracity of anything indicating that it is "the TRUTH".
I think your question ran hard into the "ick" factor before it ran into anything resembling relevance. I'm sure if you said "I've found this cute little bunny with a pancake on its head in my trunk which must have secreted its way into my car and..." I doubt few people would be advising "club it! club it!"
Also, I don't know that terrariuming it is such a good idea if you're really concerned about release/mites/parasites/OMG ECODISASTER. Small fast things have a tendency to get lost -- with great speed. (Hey, its a pretty cool spider. I say let it take over, but then again, in theory, I'm in the heartland for that stuff, so whatever).
FWIW, mail it back to someone here and have them release it for you. Should manage OK for a couple of days in a well-sealed container....
