Most point and shoots allow you to go in the ISO range of 80-1600 or maybe (big maybe) 3200. A lower ISO means that the "film" is less sensitive to light, so you'll have to have more light or a longer shutter. Try reducing the ISO to as low as possible, turning off the flash, and making the shutter go to several seconds in a pitch black room. Take a picture and move some lights around in the dark, and you'll see an illustration of how it works.
A higher ISO rating means that the "film" will be extremely sensitive. This is useful late at night when you don't have a tripod, because using a "regular" ISO setting( 200-400 produces a decent enough picture with a short shutter speed usually) will require you to have a longer shutter speed to get in enough light to make a clear image. Again, try the previously mentioned technique, except make the shutter flash short, and don't show any lights. You'll see silhouettes of the things in the frame, but not clear images. If the shutter was significantly longer, you'd get a brighter, blurrier picture because it was talking in all the light over all that time.
This is getting tangential. The point is that if the caterpillar was moving quickly, you'd probably need a high ISO rating and a quick shutter speed so that it wouldn't come out too dark or too blurry. If the thing was just sitting there, and especially if you had a steady hand/tripod, you could use a lower ISO and get away with a shutter speed of something like 1/30"
So in summation: 80's as low as point and shoots will go, and it depends on the situation to determine whether or not you should have used a higher ISO, forced a quicker shutter speed, flash, or all of the above or some mix.
