11-13 mm with a shiny coppery green appearance. There are four Poecilis species in Britain but only two are common and likely to be found in Leicestershire and Rutland. Poecilis cupreus is distinguished from the similar P. versicolor by having fine punctuations on its head between its eyes. In P. versicolor, the head is completely smooth and unpunctured. P. cupreus also prefers dryer habitats. Poecilis is distinguished as a genus by the keel on the basal antennal segments.
Prefers open, dry habitats with short grass e.g. parkland and agricultural fields but also occasionally in woodland.
