The boxwood leaf miner is a small insect that primarily affects boxwood shrubs, which are popular in landscaping. The larvae of this pest burrow into the leaves, creating distinctive, discolored patches that can lead to leaf drop and overall plant decline. Control methods include maintaining plant health, removing affected leaves, and applying insecticides if necessary. Regular monitoring can help detect infestations early, allowing for more effective management. Proper care of boxwood plants can also reduce the risk of severe damage from these pests.
