Everybody plants for butterflies and bees, but not many folks are planting for the graveyard shift.
There are far more species of moths than butterflies, and more pollination happens after dark than most people realize. While you sleep, moths are out working the garden.
Feed the adults with pale, fragrant flowers that open at dusk. Evening primrose, native phlox, yucca, and native coral honeysuckle are all favorites. Yucca is especially remarkable: its flowers are pollinated only by yucca moths, and those moths depend on yucca in return.
Feed the caterpillars too, because caterpillars are baby bird food. Oaks host more moth species than almost any other North American plant, and native cherry, willow, birch, and spicebush are all excellent hosts.
And the single best thing you can do costs nothing: turn off the porch light, or switch to a warm amber bulb. Artificial light at night disrupts moth navigation and behavior.
Plant the flowers, dim the lights, and the night crew shows up in droves.
