Thanks Harold. I am still learning how to light up the macro subjects using my flash. May be I should have set it off remote rather than on camera. Do you think ring flash will help?
I assume that by "remote" you mean off the hot shoe, perhaps radio-controlled.
You will find many excellent images here, taken with a single flash on the hotshoe but usually with strong diffusion. My personal preference is for the main flash on a bracket so that it is to one side and pointed downwards, with another to the other side, aimed about horizontally, The stronger unit would be diffused. I mount the second gun on a clamp on the lens or tube barrel. The problem is that a small gun moved forward can become the dominant light source.
If you want TTL metering you need either a suitable cord(s) or RC. I trigger mine with a kit pop-up on the hotshoe, which may or may not contribute some light but is primarily there to let the camera control the light output by RC.
I sometimes detach flash guns completely when they can be placed on the floor or be othrwise supported. This gives you much more flexibility for angle or intensity.
Ring flash has its uses but is probably best avoided until you are comfortable with conventional flash. It is particularly tricky with shiny beetles.
Prior to using RC I mainly used manual flash, calibrated for various magnifications and (nominal) apertures. That gives consistent illumination even for very dark or very light subjects.
All of the above is for flash as the main illumination. As you are supplementing daylight with fill flash you need the equivalent of my second unit, either on TTL, calibrated to be metered for reduced power or, more simply manually, on reduced power if that is needed.
