Are these Tansy Beetles?

010620111139.jpg010620111137.jpg010620111136.jpg010620111138.jpgHello,

 

Found these two beetles together on a riverbank.  They were on some dock leaves and one is clearly female with an enlarged body with a male locked on to the rear.

I do not wish to disclose the location at this time but wish to confirm that these beetles are Tansy Beetles,

 

Regards

    No, they aren't Tansy Beetles (Chrysolina graminis), but a  related species: the Green Dock Beetle Gastrophysa viridula (DeGeer, 1775).
    This species has smaller body size (4-6 rather than 8-11 mm) and females with this typically enlarged abdomen.
