Bee Shortage? Or un-sprayed FLOWER shortage?

“Watching the huge plumes of wild bees of EVERY size and description, hundreds and hundreds, swarming with great industry over our cilantro bed [which is in full flower]
I can only conclude that if you plant it,
and then • let it bolt, and go to seed •
they will come…maybe there would be more bees if we all just set the table for them?
Maybe the REAL shortage lies in the bees not having enough of the right kind of organic flowers…and the smaller the bloom, the more popular they are:
dill, cilantro, oregano, catnip, celery, onion, mustard, bok choy, broccoli, let them go to flower!”
–George Stoddard

“Wild insects pollinate crops more effectively because an increase in their visitation enhanced fruit set by twice as much as an equivalent increase in honey bee visitation. A high abundance of managed honey bees supplemented — but doesn’t substitute [for] — pollination by wild insects.”
