A lot of plants aren’t pollinated by bees. There’s pollinator wasps, flies, moths, butterflies… even birds and bats are pollinators

The earliest angiosperms appeared in the Cretaceous. This is after the appearance of Hymenoptera (Jurassic) and Diptera (Triassic). While a nice story, this needs additional substantiation. An alternative explanation is likelier imo.

Living fossils, like Ginkos

Magnolia make one of my favorite smells on earth. We have a huge one in front of a house we have moved away from and back to many times. The intoxicating smell when I mow the leaves and seeds beneath it is something I want to keep forever. I collected the red seeds and put them in a bottle with alcohol and I go back and smell it often to remember. The house flooded four days before closing on selling it, so we got more time with the house. We are wrapping that up and we will say goodbye to that old house, and it’s now quite huge magnolia in the front. I never knew the flowers were pollinated by beetles or why the scent smelled like that. I collected seeds last year and cold stratified a bunch all winter in our fridge. I planted them this spring and 7 survived the process and are now growing in red cups in my new house.

Mountain mints are also pollinated by beetles—and a bazillion other critters. They are extraordinary pollinator magnets. Beetles, bees, flies, wasps, mosquitos (!), moths, butterflies, ...

A recent study of just a few mountain mint species (https://doi.org/10.1080/00222933.2024.2411072) found that they attracted a crazy variety of pollinators. Check the supplementary materials for the full list.
