According to the Kama Sutra, oriental book of instruction, there are some seventy ways of making love. It has been claimed that only the camel knows the last one, which is why he looks so superior.
Much later, in his celebrated Let's Make Love in 1928, Cole Porter warbled, "And that's why birds do it, bees do it. Even educated fleas do it . . ." So when it comes to moving pollen from male stamen to female pistil, the ways could, and indeed do, vary.
Of course, Cole failed to mention among many other animals, bats and gnats, flies and wasps, skinks and geckos, lemurs and honey possums . . .amongst others, although perhaps not fleas. But we are getting ahead of ourselves.
