Curious about why you'd want to pay attention to that f/number on your camera settings? Consider:
An Ecuadorian Ectatomma ant photographed with the aperture wide open, f/2.8
The same ant photographed with the aperture closed down to f/13. The flash power was turned up to compensate.
Same subject, same lens, same camera, very different image.
