Nice shots, Jeremy. What are those bugs?

I like the shots - especially that green thingy.
Could somebody please explain what the extension tube does? I've never used one. Also, if you could provide a product description that would work or perhaps a link to Amazon or B&H, I'd be grateful. I wouldn't even know what to buy (if I felt like buying something).
Thanks,
Will
p.s. My more recent pictures don't look as good here in this forum as they should. Does the forum uploaded degrade them as it uploads them?

Late this afternoon, the orb weaver in my front yard finally allowed me to try again. What was different this time?- It was less breezy than yesterday so the web wasn't floating around as badly.
- I stopped down to f/16
- I (mostly) used flash
- Dropped ISO to 200
- I tried to get lower on the spider's top side so I could see its eyes. But I'm afraid that I still don't know where the eyes are - and that makes focusing on 'em a bit tricky.
What hasn't changed is camera (K10D) or lens (Tamron 70-300 macro).
I tried using AF.C (continous auto-focusing) and also tried tying auto-focusing to the shutter button. (Usually I have it tied only to the AF button.) But I ended up getting the best results focusing manually.
Anyway, results are improved. I'm attaching two samples; view short slideshow of full gallery (five shots total) by clicking here. I had a little trouble with my radio triggers (trigger's battery might be weak) so I ended up with the Metz 58 in the hot shoe, and I think that means that the lighting wasn't optimal (too direct). But it's certainly an improvement.
Thanks to everybody - especially flippedgazelle. I'm going to have to practice a lot to get some shots as good as the ones you posted, but it appears that I am teachable. :-)

Stop posting those great photos or I'm going to give up and go back to shooting people! :-)

I agree, in fact, I blogged about this very thing recently. But I was having problems FINDING his eyes and getting the light right. I've since read that it's a behavior of the orb weaver to stand in the web facing downwards. To be honest I was a tad nervous about crawling underneath the web. Perhaps one prerequisite for successful bug photography is getting over your fear of bugs. :-)
I noticed the spider was back in the web about 5 minutes ago. Grabbed the camera and the Metz flash with a Flashwave radio trigger and headed outside. The spider saw me coming and skedaddled back into the tree. I would love to sit outside and wait patiently but I have work to do, so I'll just have to keep trying until he stands still for me again.
Glad to hear that. I'll be getting that lens or the Sigma 105 next, probably. How close do you have to get to photograph something like a spider? I prefer to stay farther from the spider than the spider can jump.

Thanks, gazelle. I like your shot. That's more like what I'd LIKE to get.
Yeah, I noticed the dust too after I'd finished post-processing.
The spider seems to have gone away for the afternoon. When he comes back, I'll try again with some extra light from a flash and perhaps a smaller aperture.
My brother-in-law says he heard a lecture from a guy who shoots bugs here in Dallas who went to using a compact camera (fixed lens, smaller sensor). Why would he have done that [i.e. abandoned DSLR for compact camera]? Greater depth of field from the smaller sensor?

I noticed yesterday a spider had built a web in our front yard and caught a fly. I very seldom try to shoot macro - flowers OR insects - but I could not resist the temptation. I wasn't UNhappy about what I came up with and I'm not looking to become a prize-winning bug photographer (like, for example, Thomas Shahan!). But I would like to know how to do this a little better, especially if it doesn't involve spending money. :-)
The attached shot was taken with a K10D and a Tamron 70-300 f/4-5.6 LD Di macro, set to macro mode. ISO 400, f/8, 1/350th sec. It was late afternoon and the sun was pretty good. I did not use flash. The whole small gallery can be found here.
I was of course focusing manually. I was dealing with what I thought was a serious problem: there was a bit of a breeze and the spider's web was rocking back and forth an inch or two, so it kept going in and out of focus. I decided that using a tripod was out of the question for this reason.
I have several questions.
First, what exactly does it mean to put the Tamron 70-300 into macro mode? I know how to lock the lens to "macro" using the switch on the barrel. I just don't understand what this accomplishes, if anything. Is shooting at 300mm in macro mode different from just shooting in normal mode at the same focal length?
Second, is this the wrong lens for this kind of thing? I have a Sigma 18-50 f/2.8 macro lens. But using the Sigma lens requires that I get so close to the spider that I'd almost guarantee either (a) the spider would run away or (b) the web would sway into the camera, causing the spider to crawl on to my camera, bite me in the hand, and cause me to lose all future interest in spider photography. So I decided to use the longer lens, which allowed me to shoot from a distance of a couple feet.
Third, I have the feeling I'm probably doing everything wrong here. Any suggestions about alternate approaches? For example, should I use flash and stop the lens down even further, say to f/11 or f/16?
Fourth, what should I be going for here? I'm not even clear about that. I seem to have gotten some part of the spider's body - a leg or something like that - in nice sharp focus in some of my shots but depth of field was quite shallow. Should I be happy with that, or should I be trying to increase depth of field so that the whole spider is in focus?
Thanks in advance.
