Eye-catching Insects (3): Dock Leaf Beetle at WWT Llanelli

I am not entirely sure whether the top two photos show Dock Leaf Beetles (Gastrophysa viridula). I think they do, but thanks to Stuart's photo and commentary here, I feel relatively certain about the ID of the Beetle in photos 3 and 4.

You can read more about these beetles in the Cabinet of Curiosities blog belonging to Phil Gates, a Guardian Country Diarist ... here.
