I went for a walk near my house and saw some small, shiny green beetles on some dock leaves. I later found out that they are called Green Dock Beetles. I think this one is about to lay some eggs. 
They lay their eggs on the underside of the dock leaf. The larvae, that hatch from these eggs, are brown (I’ll have to wait to get a photo of them). Mrs. Madden
That’s a lovely beetle – we will have to look out for green dock beetles when we’re out for our daily walks!
