During my visit to the American Museum of Natural History, my astute scientific eye was able to catch many valuable details... including those involving copulation.
The butterfly room was full of it!
And this one female (in the middle) was being seduced non stop, even by some males of different species. They'd hover over her in a blur, dipping and dancing.
And then there were the reptiles...
The box turtles looked a little awkward.
Dance dance dance!
The toads were going at it as well:
Makes me wonder why they didn't show any mammal sex? (that I had seen, anyway). We were going through the museum pretty quickly to see as much as possible, so I may have missed some other good shots. But I thought these were pretty fun.
