A metallic sheen on the Goldsmith Beetle gives it the appearance of the famous precious metal that is just as difficult to find.
The Goldsmith Beetle is a type of Scarab beetle. Borders of emerald green ring the thorax and dot the leg joints. Short white hairs protrude from under the thorax. A small cluster of brown marks sit in the upper corners of the thorax, near the head. The elytra have a fine texture of tiny dark pits that form lines down the wing coverings. The yellowish-gold beetle is often found in areas near water like coastlines, creek sides, and along the banks of streams (much like gold itself). This herbivore feeds on the leaves of woodland trees like aspen, cottonwood, and willow. Immature grubs chew away at plant roots while still underground.
