Once hatched, larvae feed inside the leaf for months, living within yellow “blisters,” where they’re protected from natural predators and environmental elements. Life Cycle of the Boxwood Leaf Miner Because the leaf miner tunnels into the flesh of your leaves for protection in colder months, there is a short window for optimal treatment each year. This treatment window is based on the lifecycle of the insect. The lifecycle below is typical in regions like the Northeast and Pacific Northwest, and generally occurs earlier in warmer climates.
