| 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! |

| There are several insects that will munch on thistle, as well as a few insects that use thistles as an alternative to the prefered plant. |

| Thanks but I don't think that is it unless these are eggs. I wonder why only the thistle and only the stems? I'll get a picture as soon as I can get outside. :) |

| That would be it. I wonder why I haven't seen them in the past and we have had 2 years of rather soggy summers. I thought aphids like it dry? |

| Aphids come, aphids go. It may just be a good year for them or they finally found your plants. |

| honalee, you must be thinking about spider mites (liking it dry...so they say). Aphids thrive in all kinds of weather, climates, temperatures, humidity levels, etc. |
