Comparing moths

I have thousands of images of moths on my laptop. There, I said it. It's not a fact that I'm proud of, but I had to get that off my chest. The number of photos seem to have slowly built-up over a period of four years of moth trapping, and whilst many will never see the light of day, you'd think that with so many photos at my disposal, at least one or two would be worth sharing.

Recently, I had the amazingly original (not) idea of placing images of similar species side-by-side to create mega images; 'comparison shots' if you will. I've made a few so far, but over the coming weeks (and months) I hope to get a few more photographed in front of a blank background, as my on-going quest to procrastinate from coursework continues.

Now you know the difference between Pexicopia malvella and Bryotropha terrella, don't you ... DON'T YOU?

Would it be helpful to add a few arrowed annotations describing diagnostic features, or would that just clog up the image? Let me know what you think...
