High-tech imaging under UV light shows which parts go where when millipedes mate

Scientists have a pretty good handle on how the birds and the bees work, but it comes to mating, almost all millipedes have been a mystery—until now. For the first time, researchers have puzzled out how these tiny creatures' complex genitalia work, thanks to new imaging techniques and blacklights that make the different tissues glow. The findings are published in a new paper in the journal Arthropod Structure and Development.
