Length 2.5 - 3.5 mm; upper side shiny metallic; pronotum (green to gold or coppery-red to violet) and elytra (blue, green-golden or violet) differently coloured; elytra with completely regular, simple rows of dots, the spaces between which are occupied only by extremely fine, often barely visible dots; pronotum with a distinctly pronounced transverse furrow at the back; dotting of the pronotum strong and very uneven; basal half of the antennae light, gradually darkened towards the tip; front and middle legs monochrome light.Biology:
Crepidodera aurata is a macropterous and airworthy species that forms one generation per year. The imagines can be found on their host plants from May to October (with peaks in late June and mid September). They mostly live on willows [e.g. goat willow (Salix caprea ), almond willow (Salix triandra), crack willow (Salix fragilis), basket willow (Salix viminalis) and white willow (Salix alba)], less frequently on poplars [e.g. aspen (Populus tremula) and black poplar (Populus nigra)].Crepidodera aurata hibernates as imago. After a maturation feeding, the eggs are laid. The larvae develop in summer and live at the roots of willows. The new generation can be found outside from late summer.
