Blue flower chafer
This small chafer is common enough around flower beds and crops that Japanese naturalists call it a human associated insect, rarely far from gardens and fields.

The Blue flower chafer is a small, rounded scarab with a metallic green to bronze body flecked with pale markings, much smaller than the large sap feeding chafers it sometimes shares flowers with.
Adults visit garden and roadside flowers by day to feed on pollen, and are common enough around cultivated plots to be considered a familiar dooryard insect across their range. The species overwinters as an adult and produces one generation each year.
