Usually there are so few of these that damage is minimal but conditions can exist where they can become major pests. If hand picking (early morning is the best time) is not feasible then Insecticidal Soaps may be of some help, or possibly Neem Oil, and then if absolutely necessary pyrethrin based dusts or sprays used with real care since that is a broad spectrum poison. Eggs are laid in the fall in stalks and stems of border plants mostly. Here is a link that might be useful: About the fourlined Plant bug

I cannot find any images, either, most likely due to the fact that the insect deposits the eggs directly into plant stems. Look for this eggs near the shoot tip on host plants. One description described them as 'banana-shaped', laid in groups of 6 or so, in slits along the stem. They over winter as eggs, so good housekeeping is important. Look for their egg clusters in the winter and prune them out.

Could be cyclamen mites - I've had the same problem on a few different plants incl. an S. Divinorum, pretty bad, actually, and very similar to the pics posted. Well, curled leaves to me is the first sign of someone nesting underneath, so I looked. And saw nothing. Then looked again. And a tincy-wincy whitish thing appeared to move across. Well, out came the microscope, and yep, it's a cyclamen mite, positive ID on a few female species from different plants. Now, saying they're small means understating things by a few orders of magnitude: you need a 100x microscope to count legs, so you get the idea. At this magnification a pin tip looks like a sphere, and you still couldn't read what's tattooed on the mite's butt. Interestingly enough, they manifest themselves sort of differently on mango plants that have heavy, waxy leaves, but the idea is still the same - browning (like in case of a bad burn) and crookedness of the young leaves. At any rate, I've searched the web and those mites seem to be fairly common and - bad news - fairly hard to get rid of, the last resort measure being soaking them in 100-110F water for half an hour, something I am trying literally as we speak (just put plants in pots into a bathtub full of hot water). I'll see how it goes, but I've seen those mites dying in a drop of water under the microscope in about a minute, so it might work. I'm hoping I won't kill the plants. Makes me think - I've read on some funny sites that those symptoms are very common to S. Divinorum, but "it's a bit of a mystery" - nobody's certain, most authors contradict one another and the best advice I've seen was to try changing every variable one by one to see what works. Now, given that they are all derived from a small progenitor stock and the number of places you can get cuttings from is limited - could it be that they are all infested with mites? It's hardly surprising that mites haven't been notices in the past: as I said, it takes some looking. Thinking about the spread of infestation across my plants and its apparent chronology, I can only suggest that mites were brought on the cutting I planted, there are no other possible sources like other plants or soil. If you want to check your plants, get a really good magnifying glass and check the undersides of the leaves for tiny, 0.1mm or less, bugs. Some are moving fast. And BTW, it appears to be highly contagious, so as most sites suggest, step one is isolating the infested plants.

i ve been spraying with insecticidal soap and they seemed to react to that, i have been monitoring for the past couple of days and spraying newly detected bugs.
