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.
Japanese Earwig
A montane earwig found in the mountains of Japan, known for extreme maternal care. Females guard eggs and first-instar nymphs in burrows under stones.
Did You Know?
Japanese earwig mothers sacrifice their own bodies as food for their young — the nymphs consume the mother after she dies.
