Noble Chafer

Gnorimus nobilis can reach approximately a body length of 15–19 millimetres (0.59–0.75 in). These beetles have the pronotum and head covered with dense medium-sized dots. Elytra are covered with dense, coarse wrinkles and small, small dots. They have a green metallic-green body speckled with white. They show a brilliant iridescence that can vary from gold to copper or violet. The sides of the abdomen and the pygidium are also gold-green with large white spots. The bottom side varies from bright coppery to black. The related species Gnorimus variabilis is easily distinguishable. In this species the elytra are not green metallic, but black, with white spots. In addition, the shape of the pronotum side edge is laterally weakly s-shaped, while in Gnorimus nobilis it is simply rounded. Gnorimus nobilis is also rather similar to the more common Cetonia aurata, but in the latter the middle and hind legs are toothed, whereas they are smooth in the Gnorinus nobilis. Moreover in the noble chafer the scutellum forms an equilateral triangle.

This species is widespread in most of Europe (Albania, Austria, Belarus, Belgium, Bosnia and Herzegovina, Bulgaria, Croatia, Czech Republic, Denmark, Estonia, France, Germany, Greece, Hungary, Italy, Latvia, Liechtenstein, Luxembourg, Montenegro, Netherlands, North Macedonia, Norway, Poland, Portugal, Romania, Russia, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey, Ukraine and United Kingdom). It seems to be declining over much of its European range. In Britain this beetle has been losing its habitat, and its populations shrinking, for more than a century. The beetle has been recently seen at a handful of sites in the old English fruit-growing regions of Gloucestershire, Herefordshire and Worcestershire.

The genus name Gnorimus derives from the ancient Greek γνώριμος, gnōrimos meaning 'famous'. The species name nobilis (Latin) means noble.
