I have an infestation of little red bugs that hop quite far when you disturb them. They even make a sound when a bunch of them hop at once, sort of like lots of mini grasshoppers. They ended up all over my clothes when I was trying to harvest some veggies. They are on top of the leaves (not underneath) of everything in my vegetable garden. They are perhaps twice the size of a period. I can't make out any features because they are so small, but they are clearly visible as little dark red spots all over the plants. I saw a few on my parsely, then I was busy and didn't go out in my garden for a week or so. Now they are everywhere! The only damage that is visible to the plants so far is that a few of the bugs seem to leave behind a small black spot when you knock them off. I have been reading up on spider mites, but it sounds like those are too small to see and live underneath the leaves of plants. Any ideas?
