This Shield bug appears to have just moulted. It walked away, leaving what looks like its old skin clinging to the branch. The other bug in the photos, on the top of the branch, was walking backwards and forwards, almost looking like it was interested in the proceedings.
These ten tiny green eggs were laid on an outdoor table, under a hat. Ten days later, ten tiny bugs emerged. Two days later they had left to find their way in the world. Order: Hemiptera. I think they are Family: Pentatomidae.
