Ancient Insect Pollination

80% of today's plants rely on insects for reproduction by carrying their pollen grains. Over time insects like bees and butterflies have co-evolved with plants to carry their pollen and in return receive food. Recently in a piece of Cretaceous amber from Spain six small insects ,now classified as a new genus (Gymnopollisthrips), had specialized hair rings to collect pollen grains. These insects are over a million years old which makes them the oldest record of insect pollination. It is suspected that the insects used the hairs to carry pollen back to their larvae.
