During the day our showy goldenrod (Solidago speciosa) is visited by the usual sun-loving suspects: bumble bees, sweat bees, hover flies, butterflies, and so on. I was curious about what happens after dark, though, so I just popped out to have a look. It’s nearly as active at night, too, but with a different set of species!
