Gravid & Mating Leaf Beetles

The female of this Leaf Beetle species is normally very small (like the male) with the elytra being the limit of her length. However, when gravid with eggs, she can expand the abdomen to 5 times her normal size. The male is barely able to hang on. I wonder if she can return to her original size once she deposits her eggs. There were several of these couples scattered about on the bushes. Photos 5 & 6 are of a different couple than photos 1-4, but the same species. Family Chrysomelidae.
