Grape Flea Beetle

A small, metallic dark blue beetle with enlarged jumping legs that feeds on grape buds and young foliage. It can cause significant economic damage in vineyards by destroying developing buds.

💡

Did You Know?

Adults emerge in early spring to feed on swelling grape buds, and a single beetle can destroy multiple buds before leaves fully develop.

Bloody-Nosed Beetle

A large, flightless, domed black beetle that oozes red fluid from its mouth when threatened. The secretion contains distasteful chemicals.

💡

Did You Know?

The red defensive fluid is actually hemolymph, the beetle equivalent of blood.
