What eats aphids? Green lacewings and lady bugs. I went outside with my hand lens to see if I could find any, but came away with more observations. But should I be spending my time exploring summer tree life, or removing the gunk on my car, or going through 100 emails past due? By the time I figured this all out, it was late afternoon.
Note to myself, "if honeydew has dripped onto your car or patio furniture, remove it quickly with an appropriate detergent-based product and a soft cloth. Two tablespoons of vinegar in a gallon of water works well on outdoor furniture ." Second note to myself, the emails can wait.
