Bees do it.
As part of her research, Ashman sits quietly next to a group of tiny numbered pots with s ingle flowers planted in them. The flower the bee selected looks similar to all the others, with five bright white petals and the female reproductive organ, the carpel, reaching up from the middle towards the sky. Ashman didn't tell the pollinators that not all the flowers they're landing on are female. Female flowers have only a carpel, while hermaphrodites also have the male reproductive organs, or stamen. To help determine why pollinators land on hermaphrodites twice as often as on females, Ashman put the hermaphrodites in drag.
