I began photographing bugs and trying to identify them as a means to discovering who was in my garden and what they might be up to. The garden quickly became too small an arena and my camera began to accompany me on walks along near-by trails. Soon I could hardly go anywhere without one or two cameras tagging along. It's been fun, it's been interesting, and it's been educational.
I try for quality sightings; in focus, multiple views from different angles, and as much as possible a standardized format. It all helps in identification.
