I have found these little black bugs on my plants. They seem to always be at a leaf joint, but I did find some in soil. They don't fly and spraying with neem oil seems to kill them on contact. They must eat at the leaf joint or suck fluid from that area because once they get on a plant all it takes is the lightest touch and the leaf falls off. Does anyone know what these plant munching pain in the butts are?
