Autumn leaf identification quiz: can you identify these 10 trees? Hence their nickname, the June Bug. Steps within an IPM plan include: Monitoring the active life cycle of the chafer beetle by implementing Chafer Pheromone Traps from May through to June will help to reduce the adult beetle egg laying and give valuable warning that chafers are present. Adults are 2.5-3cm long, and are common in the south of England and the Midlands. Cute and clumsy.
