Well done Christine! I was just searching for a shieldbug for Sandy, it's one which feeds on harmful pests.
My garden was full of aphids when I first moved here over 13 years ago, once I got to work making beds with a variety of plants the natural balance soon sorted itself. I know now if I see aphids I don't have to do a thing, the predators make quick work of them. I feed birds too, Sparrows are increasing and they are one of the best aphid eaters.
It looks like your garden has it's predators too Tee!
