Illustration of a Darwinylus marcosi beetle covered in pollen grains (yellow). In 2016 a specimen of this beetle was found preserved in 105 million year old amber in Northern Spain. At this time, in the mid-Mesozoic, there were very few flowering plants (angiosperms), so this pollen would have belonged to a gymnosperm (seed-producing) plant. D. marcosi had been feeding on the pollen, chewing the grains with its mandibles (jaws), demonstrating for the first time a fourth major insect pollination mode. This was a mutualistic relationship, with the beetle receiving nutrients and the plant being pollinated. | |
