At the high end (from my POV) -
Before you rip up your basement
, you can try
1. Find the minimum object distance of your camera. This should be specified in the back of your manual. I think you are too close. Your camera cannot focus if you are closer than the specified distance. You can check the manual for this distance. Also, check if your camera has macro mode.
If you have a macro mode, switch to that and practice focusing using auto focus and manual focus. Give you camera autofocus to work, some cameras have to "hunt" for the focus. For e.g., my Canon A80 is a pain in macro mode because it is constantly hunting for focus, my SLR will come in spot on within a second of pushing the button.
If auto focus does not work in macro, use the manual focus to get a sharper image.
2. Looks like you are out of light too. Get closer to a window or get a better light source - a lamp or a flash. If you use a window, you can try putting white printing paper vertically on sides to kill the shadows. If using a flash, get a diffuser or create one by pasting wax sheet from kitchen on the flash.
3. Find an even background. Do NOT use white, it will throw your camera's light meter off. Use either light blue or light grey. Best is just get a grey card from a camera store and use it. It will give nice even background and the light reading will be fine too.
Hope these help. Looks like an interesting fly.
