Jack, The truth is that I was very lucky, I was cleaning the garden and I noticed the insect immediately stopped what I was doing and grab my camera, what took me the most time was the angle, I took many photos but I did not like them until this was the best I liked it, I'm not entirely happy since I would have liked to have more space between the back petal and the insect's mouth.
Do you also keep an eye on your shutter count as well ? I found that when shooting insects, requires a lot of images to be taken, which at some point affect shutter count. You having camera with you all the time ?
