Watching the light fade last night, I see leaves grow indistinct, dark masses without color. 

Searching for bats, I see blurred forms cut through the darkness, visible only when they cross a patch of still-blue sky.

As sunlight vanishes, fireflies rouse themselves from the ground, blink and twinkle as they flutter their way to the treetops.

Closer to where I’m sitting, the deck lights snap to attention. They’ve been storing sunlight all day and now release it.

Two types of night light on an early July evening.
