Swollen-thighed Beetle

Oedemera nobilis Copyright: Peter Harvey

Swollen-thighed beetle Oedemera nobilis is abundant in spring and early summer on various flower species, and commonly found in Essex and southern England. They are a brilliant metallic green or blue colouration which often has distinct red overtones, and the elytra are strongly narrowed towards the apexes, not hiding the membranous hind wings. Males are very conspicuous by their swollen hind femora and bright green colour. The beetles feed on pollen and nectar of various flowers.

The best distinguishing features are the brilliant metallic green or blue colouration which often has distinct red overtones, the elytra strongly narrowed towards the apexes, not hiding the membranous hind wings, and the swollen hind femora of the male.

The similar Oedemera lurida is generally smaller than O.nobilis and a dull sage green in colour. The elytra are only slightly narrowed, towards the apex at least three quarters of the width at the shoulder. Males have only slightly thickened hind tibia.
