At first, MOH and I saw this little spider-like being running around on one of the chocolate mint shoots, and we thought it was the teeniest, tiniest itsy-bitsy spider. To be fair, MOH saw this first, not me.
The web it was making when we first saw it.
Turns out these are several itty bitty spider mites, not the sorts of things one wants to have on plants.
Here's one of the little nasties up close; you can see not only the strange legs, but some of the little hairs coming out from its body.
...and another enlargement. I googled "tiny green spider" and finally came up with photos of spider mites, at which point we went directly into eradication mode. These appear to be twospotted spider mites (Tetranychus urticae). Hopefully, they won't be too hard to kill. They suck the blood, I mean juices, of stems and leaves, and are generally undesirable.
Here's one hanging out on it's little web. Oh, so cute.
