Plants mimic scent of pollinating beetles
Date:4/3/2012

irst members of the arum family to be pollinated by beetles not appearing until around 40 million years later. "In the course of evolution, the arum family mimicked the scents of scarab beetles to attract pollinating insects more efficiently," says Schiestl.

Coevolution less common than assumed

In research, coevolution is regarded as a driving force behind the development of a mutual adaptation between two organisms. However, this is not true of the arum family, which developed its scent along the pre-existing communication of scarab beetle scents. "Coevolution between plants and pollinating insects might well be less common than we thought," Schiestl concludes.
