Tiny black....bugs? on Canada Thistle
Was in the garden weeding today and I found thistle plants with tiny black spots/bugs on the stems. Only on the stems and not on any of the other plants. Peonies, irises, delpiniums, lilies, raspberries, other weeds and grass not touched. Any idea what this/they are? Not that I care too much, just curious. I wish something would destroy these horrible plants!
