Pelidnota punctata

Grapevine Beetle

Pelidnota punctata, Grapevine Beetle

Family: Scarabaeidae

Subfamily: Rutelinae

Length: 18-26 mm


Pelidnota punctata boasts black two spots on the pronotum and six on the elytra. The legs and undersurface may be deep metallic green, or else pitch black.

Adults are a pest of wild grapes and of vineyards, while the larvae feed on the decaying roots of various species of trees.

As Philip Harpootlian points out, the Grapevine Beetle is a variable speciesso much so that T.L. Casey named ten species and subspecies in 1915, names that were later merged back into Pelidnota punctata.
