But on June 27, the mass suddenly changed dark (all over the course of one night) and soon it was alive with dark movement. To be honest, it was a little gross. Over the course of a day, the imperceptible dark mass began differentiating into individual insects. A search of the net appears to give these a name: stink bugs!
Now the stink bugs have all gone. First they moved away from the eggs casings and then a few would return at night, hugging close to the cast off shells. Eventually we saw even these climbing higher on the glass until - poof! - they were gone.
Today (July 2) we had a butterfly (moth?) land on a nearby window. I was able to take a picture of it's underbelly and its delicate wings, backlit by the late-day sun. It's not a beautiful butterfly - no brilliant colors or fantails - but it's exquisite in its simplicity, plain and ordinary but as unique as a snowflake.
So you have your choice today: stinkbugs or a butterfly. Either is a nice choice and fits in its special cog in this natural world.
