Rosemary Beetle

Fascinating facts about the Rosemary Beetle

• At just 5-8 mm long (0.20-0.31 in), the rosemary beetle fits on a fingertip yet sports vivid metallic green and purple stripes that flash like tiny armor. Its wings are so short it can only buzz a few meters before landing, so it mostly walks across rosemary leaves hunting for food. This tiny size lets it hide among the aromatic foliage, making it hard for predators to spot and allowing it to feed continuously on the plant's surface without being brushed away.
• The beetle's menu is a fragrant buffet of rosemary, lavender and thyme, all members of the aromatic Lamiaceae family. This close tie to culinary herbs means gardeners can spot infestations by the tiny beetles on the very herbs they harvest for cooking.
• Although its name suggests a New-World origin, the rosemary beetle is native to southern Europe, North Africa, the Near East and the Middle East. Its spread to the United Kingdom began in 1994, and by 2002 it was already common across London, racing outward to neighboring counties.
• In the Mediterranean, females lay eggs in late summer on host-plant leaves, and the larvae, banded from whitish to blackish, continue growing through the cold winter months. After about three weeks as a pupa, the adult emerges in spring.
• Gardeners fighting rosemary beetles are advised to hand-pick the insects or shake them onto a sheet of paper, especially when the herbs are meant for cooking.
