This thread reminds me that I haven't been out chasing butterflies for a while, and also that I haven't been organizing my pictures very well recently.
I had moderate luck with a long lens, since a whole butterfly in the frame is not really a macro shot. This one was with D3200 and 55-300 lens. Unfortunately even at ISO400 that one gets a little noisy. Unfortunately we also don't get a lot of variety in our butterflies, but they're nice and big and fairly easy to hit.
