Which is weird, because today most gymnosperms are conifers - plants whose reproductive structures often look like cones and are pollinated by wind, not by insects.
Like, organs called nectaries evolved, which delivered tasty nectar rewards to pollinators - these were a new take on the old pollination drops of gymnosperms.
So, beetles may have been the insects that were best able to shift from their relationships with gymnosperms to the new resources offered up by angiosperms.
A single individual was found fossilized in 105 million-year-old amber from northern Spain with gymnosperm pollen dusted on its mouthparts, legs, and back.
The stage for insect pollination was set possibly as far back as the Permian Period, when insects are thought to have started feeding on gymnosperm plant fluids.
