John, might I suggest, build yourself a moth trap. Moths have been a thing of mine since I was a kid and I built a Robinson trap with a MV lamp on it. My interest has waned now but I still run once a month on a timer outside the back door because my kids love it. This usually catches 50-500 moths during a night, even in winter (although they tend to be grey/brown and drab during the winter here in the UK).
Thank you for the suggestion. While I certainly see the advantages to trapping moths, and I appreciate the suggestion, I personally don't trap anything. I know of people who even go so far as to "refrigerate" butterflies (to slow them down), and who then place the disabled butterfly on specifically-chosen flowers for added effect, and then they can just fire-away and get some really nice images.
But that kind of thing takes the magic out of it for me. I just photograph what I am lucky enough to come across
