Sorry I can't help id the bug...great picture...how did you get it to appear within your post instead of as a separate attachment....?

Not an aphid.

It's a young true bug, family Hemiptera. Don't know which one until you can post an image of an adult. Could be a lygus bug which can be a pest if numerous.

Thanks! To add photos I just use the following HTML code. With, of course, the page on which my photo is located inserted between the quotation marks.

You do have to have your photo posted on another web site for this to work. And you also have to enclose the whole code between the following sort of brackets:

I think I may have identified the bug as Poecilocapsus lineatus or Four-lined Plant Bug. Now I just need to find some predators for it!

I think that predator will be you!

That four-lined bug is very fast and much trouble. I have been fighting them for years. I hunt them every day. Insecticidal soap works good when they are young. It is sometimes easier to shoot them with a spray than try to squish them since they are so quick. Clean up dead stems in fall as they lay their eggs in them. Search the internet for info about them. They are not plant killers but disfigure so many.

Yes, this bug is big trouble, and seems to prefer the new growth at the tips of the plants. So, for types that I know will bounce back fast--such as evening primrose, coneflower, rudbeckia, etc.--I often just snip off those tips. And drop them in a bucket of water to drown the bugs. This probably does make the plants branch out better, but it also sets the bloom time back a bit. And makes the garden look ratty when it should be looking its best.

About the only predator I could find listed for four-lined bug is the jumping spider. And I suspect it's probably not widely available for purchase! So I'll probably be doing a lot more snipping.

Assassin bugs (several kinds), mantids, birds, and more are natural predators of such insects.

I don't use any oils or pesticides for insect control as I grow organically. google Arbico. they specialize in beneficial insects. I ordered three praying manti egg cases. one for my yard and for my neighbors on both sides. one egg case hatches abou two hundred manti. They devour every insect you hate. and once they live out their life cycle they lay their own egg cases. so now I have an ongoing population of manti. I live an hour north of death Valley so its a desrt hot blazing summers freezing winters if my manti can stay alive year after year your area will support them as well. also consider Ladybugs these are literalyy the toughest bug in the pack they eat every single pest bug you can imagine problem is when they eat everything they move on to find more food. I even take my baby manti indoors to work over my bonsai and houseplants I leave a couple of windows open all the time for my cats to get in and out. so manti have an escape, or entrance if they choose. I grow vegetables, tobacco, fruit, housplants and bonsai. this was a permanent and inexpensive solution to my bug problem. Good Luck!!!!
