💡

Did You Know?

Despite its name suggesting holly (ilex), it feeds exclusively on oak and was misidentified when first described.

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.
