I'm with Dave on this, macro, but shooting bugs is what I love, but I always take my long lens with me for my other love which is aircraft.
Fortunately for me I can combine the two as the nature reserve I use for bugs is also a bombing range for the Airforce.
I was able to take an amusing photo there last year of a Chinook which was using lasers, or something similar. The crew waved to me several times and took me completely by suprise and flew towards me. I'd taken several photos of the Chinook exposures where perfect, so expected the same as it flew towards me. What I didn't realise is that they would fire the "Lasers" at me which affected the exposure. so sorry for the poor quality of the attached photo.
