We have an infestation of what appears to be hard very small brown bugs on the coneflowers. Looks like bits of soil but we think it’s infestation. Your thoughts would be appreciated. Thanks very much as always for freely sharing your wisdom. Photo attached.
I’m sorry to hear your coneflowers are being affected. The photo attached is quite blurry. If possible could you try to take another photo and resubmit? (Try zooming out a bit and pressing your finger on the screen overtop of where the bugs are so the focus pulls to one of them.)
In the meantime, here are a couple of resources with images of the most common coneflower pests to see if you can identify the insect from those lists:
