Are any of your rhododendrons looking pale? You may be bugged. If you see pale speckles all over rhododendron or azalea leaves, turn over an affected leaf. If there are smutty-looking, blackish spots on the underside, especially along the midrib, then you may be looking at the larvae and poop of azalea lace bugs. You may see adults, too. An adult lace bug is a small, slow-moving, fly-like creature about one eighth of an inch long, its transparent wings marked with a black and white pattern. Last year, Hendricks Park staff noticed damaged plants in the rhododendron garden.
