A deep blue leaf beetle that feeds on Alder (Alnus glutinosus"), often in numbers. Like many Chrysomelids, the freshly-emerged female’s abdomen is so full of eggs that it protrudes beneath the elytra and forces them slightly apart.
Formerly considered extinct, for the last few years it has been increasing from Southampton into the New Forest. This may represent an unknown relict population but are much more likely to be a recent introduction/colonist from Europe: it had long been suspected of being an occasional immigrant rather than a true native species.
