I'm not ashamed to name the Asters as some of my favorite plants in the garden. They do most of what I ask, including surviving overcrowding, heat, wind, drought, and massive infestations of bugs that help to mottle and yellow their leaves all while continuing to put out new growth in preparation for fall flowering.
Please, click on these photos for a closer view. The black dots, no doubt, are bug poop.
These are the critters. A quick glance might yield you aphids, but one really must get close for these. Their backs look somewhat sculpted and lacy, with stripes. The nymphs, which are everywhere, do not have this feature and are clearly spiny. My quick internet search yields the Chrysanthemum Lacebug or Corythucha marmorata as a possibility, in the family Tingidae or Lace Bugs. It seems these pests are named for the nursery trade plant group they prefer to infest. But they aren't touching my mums, and seem to love asters.
Bug poop? Ick.
ReplyDeletesheesh - thats no fun! Is it really bug feces? Or could the black spots be bug eggs?
