As I sort through my collections of bee photos, I thought it would be fun to try to post one bee or bee plant photo per day. This is a mason bee I saw two days ago foraging on Ontario and 20th in the Hyancinthoides hispanica (Spanish bluebells).
Observing Orchard Mason Bees (Osmia):
Look for pollen under their hairy abdomens.
Look for little white beards on males.
Good Question: Do male mason bees pollinate?
Yes, but only as they forage to feed themselves. The females visit more blossoms as they feed themselves and collect food for their progeny.
