A late summer visitor

Every summer, I look forward to a particular seasonal visitor in the garden.  The Hummingbird Hawk-Moth usually appears when the Dwarf Lilac bushes come into bloom in late June/early July.  This year, we had some unusually cool and wet weather, so if they foraged the lilacs I did not see them.

Fast forward to nearly the end of August,  I'm sitting on my front porch near dusk, sipping tea, when I hear a familiar sound.  I glanced down to where two large pots of petunias were sitting and spotted my visitor!  Have a watch!  I had never seen one so close to dark.  The sun had already dropped below the horizon, but here it was.
