Thanks JimKnopf! There was bright sunlight so I had a nice fast shutter speed, so the IS probably didn't actually make much of a difference in this case. It is excellent the moment light starts to fall off though. I highly recommend the 28-135IS. Maybe one day I'll be able to get the 100-400L IS...
The key thing for this shot was patience really, sitting still and letting the dragonflies whizz around, watching where they liked to stop and hover. The 10D does around 4 FPS so when I managed to get a reasonable shot framed I just set it blasting away!
