The hairy flower chafer is a beetle (Trichiotinus piger) that also goes by the name, the bee-mimic beetle. Indeed, it hangs out around flowers, is a plausible mimic of a bumble bee, and is a pollinator.
In other years, I have seen many bumble bees and only a few of these. This year it is the reverse: the hairy flower chafers seem to be doing the bulk of the pollinating in my yard (three pictures, below).
A hairy flower chafer is soon covered with pollen as it roams between flowers. These weeks I see them mainly on daisies.
I usually only see one of these on any flower.
But, it seems that these two have decided to become friends.
