Yesterday was a typical late summer day in our flower gardens at home.
The New England Asters, Showy Goldenrod, and Zigzag Goldenrod were practically covered with various species of bees.
This is not the best photograph, but it shows the number of small carpenter bees that we covering the Zigzag goldenrod.
The bee nesting box is almost entirely full. The larvae inside will not emerge as adults until next spring and summer.
A few of the "bees" visiting the flowers were not bees at all, such as this bee-mimicking fly on the Showy Goldenrod.
This kind of activity will continue until a hard frost kills of the blooms or the bees.
