Hi. There are several approaches.
One way is to get a 2X extender and put it behind your lens. Then you go up to 2/1 magnification ratio with a macro lens.
Another way is to crop your images.
A third way is to buy an old, manual focus 50mm lens and hold it wide open, inverted before your lens. Then you can get magnification ratio's of up to 10/1. I have friends im my nature photo club who do this with a digital point & shoot, handholding the lens in front of the camera and they get very good results.
My personal approach : I use a 200mm macro lens with a 2X extender and a TTL flash. It gives me 2/1 magnification ratio and a working distance of well over a foot, which makes it easy to approach the insects. I regularly crop, too.
Perhaps other posters can tell you about their methods, too.
