it looks similar to the alfalfa beetle.

I'm not going to discard any of my plants because of these, and don't think you should either. Their involvement with plants is transient, seasonal, not an indefinite infestation. This is about crops, but the graphic of their life cycle is helpful. Once the last generation hatches into winged adults, they fly away to hibernate. Similar to how butterflies work.

yeah insecticidal soap is a contact killer so you should spray the undersides of the leaves where they like to gather. Just repeat every week if you see them. If left unchecked they will stunt the growth of the plant i lost a cutting or two from outside to them because i was not careful enough to make sure no aphids got inside. another if not icky way to rid of them is either rub them off with your fingers though this will not work as well if they are hiding in small crevices like the tomato blossoms and the like

It should be explained that Chinese mantids are a completely equal opportunity predator. They are very successful killers of bees, butterflies, and other beneficial insects. In warm climates, they will grab anoles and small amphibians. There are numerous videos online of these big Chinese mantids capturing hummingbirds at feeders. I began eliminating these insects from my gardens many years ago, as I rely heavily on beneficial insects in my gardens and adore watching my flower areas so alive with butterflies. Once I began to notice piles of butterfly wings under my annuals and perennials......that was IT! The much smaller native mantids don't cause these issues. Unfortunately, these big, imported bad guys also attack and eliminate our native species.
